| 1 | Influence of Al-Ti-B addition on the microstructure and mechanical properties of A356 alloys显示文摘The mechanical properties (σb,σ0.2,and δ) and fracture behavior of tensile specimens of the refined A356 alloys were investigated as a function of the addition level of Al-Ti-B master alloy under both as-cast and T6 heat-treated conditions. The results show that as the addition level of Al-5Ti-1B master alloy increases from 0.1 wt.% to 5.0 wt.%,the mechanical properties of refined A356 alloys improve steadily and then decrease slightly under both as-cast and T6 heat-treated conditions. Also,they display excellent mechanical properties with σb = 231.30-258.30 MPa,σ0.2 =134.00-155.50 MPa,and δ = 8.5%-11.75% at T6 heat-treated state. The excellent mechanical properties of refined A356 alloys are ascribed to the formation of α-Al equiaxed dendrites,the improvement of eutectic structure from needle/plate-like to short-lathy/block-shaped,and the Mg2Si aging precipitation phase after T6 heat treatment. The fracture surface examined by SEM exhibits a mixed fracture mode of refined A356 alloys at as-cast state,while it reveals a ductile fracture mode after T6 heat treatment. | Zhu Man Yang Gencang Yao Lijuan Cheng Suling Zhou Yaohe | 2009 | Rare Metals2009，28，2： | 11 |
| 2 | Immune checkpoint inhibitors in cancer therapy显示文摘In recent years immune checkpoint inhibitors have garnered attention as being one of the most promising types of immunotherapy on the horizon. There has been particular focus on the immune checkpoint molecules, cytotoxic Tlymphocyte antigen-4(CTLA-4) and programmed cell death protein 1(PD-1) which have been shown to have potent immunomodulatory effects through their function as negative regulators of T cell activation. CTLA-4, through engagement with its ligands B7-1(CD80) and B7-2(CD86), plays a pivotal role in attenuating the activation of naive and memory T cells. In contrast, PD-1 is primarily involved in modulating T cell activity in peripheral tissues via its interaction with PD-L1 and PD-L2. The discovery of these negative regulators of the immune response was crucial in the development of checkpoint inhibitors. This shifted the focus from developing therapies that targeted activation of the host immune system against cancer to checkpoint inhibitors, which aimed to mediate tumor cell destruction through the removal of coinhibitory signals blocking anti-tumor T cell responses. | Eika S.Webb Peng Liu Renato Baleeiro Nicholas R.Lemoine Ming Yuan Yaohe Wang | 2018 | The Journal of Biomedical Research2018，32，5： | 8 |
| 3 | Liquid-phase Separation in Rapid Solidification of Undercooled Fe-Co-Cu Melts显示文摘The homogeneous liquid was separated into two phases,(Fe,Co)-rich L1 and Cu-rich L2,once the melt was undercooled below a liquid-phase separation temperature T sep.If the duration from T sep to T s1(solidification temperature of L1 phase),termed the liquid-phase separation interval t,exceeded a critical value,an egg-type structure was observed.By utilizing differential thermal analyses(DTA),the solidification process of the undercooled Fe-Co-Cu alloys was studied.Additionally,an immiscible boundary was obtained,which was a convex parabola with a symmetrical axis of x Cu =0.52.Depending on the relative amounts of L1 and L2,the minor phase was nucleated firstly to form liquid droplets and separated from the original liquids at the beginning of liquid-phase separation. | Ning Liu Feng Liu Zheng Chen Gencang Yang Changlin Yang Yaohe Zhou | 2012 | Journal of Materials Science & Technology2012，28，7： | 7 |

| 5 | Effect of interface kinetics on the eutectic growth显示文摘The atom-attachment kinetics at the solid-liquid interface was incorporated into the eutectic growth theory. The dependence of kinetic undercooling on the structure of the eutectic phases was investigated. Due to the introduction of the kinetic effect, the coupled eutectic growth can proceed in a wider undercooling range, but the growth velocity decreases while the minimum eutectic lamellar spacing remains unchanged. The proportion of kinetic undercooling to the total undercooling is dependent not only on the growth velocity, but also on the phase diagram. Calculation indicated that the proportion decreases as the crystallization temperature range of single eutectic phase at the eutectic composition enlarges. | LI Jinfu ZHOU Yaohe | 2005 | Science China(Technological Sciences)2005，48，4： | 4 |
| 6 | Free-volume evolution of glassy Zr_(65)Al_(7.5)Ni_(10)Cu_(17.5) during inhomogeneous deformation显示文摘Free-volume evolutions of the as-cast and pre-annealed Zr65Al7.5Ni10Cu17.5 metallic glasses during cold-rolling were investigated using differential scanning calorimetry. As deformation degree increases, free volume in the glasses always increases first and then saturates above a critical strain, while the structure remains completely amorphous. The glass with less initial free volume possesses a higher increase rate of free-volume content during deformation, and as a result the free-volume contents of all the glasses approach each other at higher strains. Coalescence of free volume in shear bands into nanovoids is proposed to be responsible for the saturation of free-volume content at high strains. | LIU HuiBin LI JinFut CAO QingPing ZHOU YaoHe | 2007 | Chinese Science Bulletin2007，52，24： | 4 |
| 7 | Growth morphology and evolution of quasicrystal in as-solidified Y-rich Mg-Zn-Y ternary alloys显示文摘A petal-like icosahedral quasicrystal with five branches,which is considered to be the representative morphology of the icosahedral quasicrystal,has been observed in the Y-rich Mg-Zn-Y ternary alloys. Moreover,the polygon-like mor-phology,another pattern of the icosahedral quasicrystal,has also been found in the Y-rich Mg-Zn-Y ternary alloys. The latter morphology results from the evolution of the former one. The growth mechanism of the petal-like morphology of the ico-sahedral quasicrystal was also discussed. Alloying composition,i.e.,Y element content,is a major factor inducing the mor-phology evolution of the icosahedral quasicrystal. | WAN Diqing YANG Gencang CHEN Sulin ZHU Man ZHOU Yaohe | 2007 | Rare Metals2007，26，5： | 4 |

| 9 | An intrinsic correlation between driving force and energy barrier upon grain boundary migration显示文摘The migration of grain boundary(GB),which plays a key role in the microstructural evolution of polycrystalline materials,remains mysterious due to the unknown relationship between GB mobility associated with specific geometry and external conditions(e.g.temperature,stress,etc.,hence the thermodynamic driving force).Combining the rate equation of GB migration with molecular dynamics simulations,an intrinsic correlation between driving force and energy barrier for the migration of various types of GBs(i.e.twist,symmetric tilt,asymmetric tilt,and mixed twist-tilt) is herein explored,showing the decrease of energy barrier with increasing thermodynamic driving force. | Bo Lin Kang Wang Feng Liu Yaohe Zhou | 2018 | Journal of Materials Science & Technology2018，34，8： | 3 |

| 11 | Microstructure of Cu_(60)Zr_(20)Ti_(20) bulk metallic glass rolled at different strain rates显示文摘The structural evolution of Cu60Zr20Ti20 bulk metallic glass during rolling at different strain rates and cryogenic temperature was investigated by X-ray diffraction (XRD),differential scanning calorimetry (DSC) and high-resolution transmission electron microscopy (HRTEM). It is revealed that the deformation-induced transformation is strongly dependent on the strain rate. At the lowest experimental strain rate of 1.0×10-4 s-1,no phase transformation occurs until the highest deformation degree reaches 95%. In a strain rate range of 5.0×10-4-5.0×10-2 s-1,phase separation oc-curs in a high deformation degree. As the strain rate reaches 5.0×10-1 s-1,phase separation and nanocrystallization concur. The critical deformation degree for oc-currence of phase transformation decreases with the strain rate increasing. | LI JinFu,CAO QingPing & ZHOU YaoHe State Key Laboratory of Metal Matrix Composites,School of Materials Science and Engineering,Shanghai Jiao Tong University,Shanghai 200030,China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，4： | 3 |
| 12 | Electromagnetic Filtration of Primary Fe-Rich Phases from Al-Si Alloy Melt显示文摘Electromagnetic filtration of primary Fe-rich phases (complex compound of AlFeSiMn) from Al-Si alloy melt containing 1.2 wt pct Fe have been studied by theoretical analysis and on a self-designed electromagnetic filtration equipment. The principle of the electromagnetic filtration is that the EMF (electromagnetic force) scarcely acts on the primary Fe-rich phases having low electric conductivity, which are then moved in the direction opposite to that of the EMF. Experimental results show that the primary Fe-rich phases are separated from Al-Si alloy melt and are collected in the filter while the melt is in horizontal flow. The removal efficiency of the primary iron-phases (77) calculated is less as the greatest flow velocity of the melt (UM) and the height of the filter (2h) are larger, while it becomes larger as EMF, operating distance of electromagnetic force (cr) and particle size (dv) become larger. It has been confirmed that the primary iron-phases larger than 20 jim can be removed efficiently by theoretical analysis and experiments. This new technique is high efficient and available for continuously flowing melts as compared with natural settling and filtration methods, which offer a possibility for recycling high quality aluminum alloys. | Zhenming XU, Tianxiao LI, Da SHU and Yaohe ZHOU School of Materials Science and Engineering, Shanghai Jiaotong University, Shanghai 200030, China E-mail: zmxu@mail1.sjtu.edu.cn | 2001 | Journal of Materials Science & Technology2001，17，3： | 3 |

| 15 | δ/γtransformation in non-equilibrium solidified peritectic Fe-Ni alloy显示文摘Through phase transformation kinetic analysis and experimental observation,the δ/γtransformation occurring in the non-equilibrium peritectic Fe-4.33at.%Ni alloys was systematically investigated.According to JMA solid-state transformation ki-netic theory,the Time-Temperature-Transformation(TTT)curves of the δ/γtrans-formation in peritectic Fe-Ni alloy were calculated.On this basis,the physical cor-relation between the δ/γtransformation and the initial undercooling of melt(T)was elucidated.The results indicate that the change of T can alter not only the overall δ/γtransformation pathways but also the transformation fraction with re-spect to each transformation mechanism. | CHEN YuZeng LIU Feng YANG GenCang LIU Ning ZHOU YaoHe | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，4： | 3 |
| 16 | Rolling-induced microstructure change in Zr_(65)Al_(7.5)Ni_(10)Cu_(12.5)Ag_5 bulk metallic glass显示文摘The microstructures and free-volume evolutions of as-cast and pre-annealed Zr65Al7.5Ni10Cu12.5Ag5 bulk metallic glasses during rolling deformation have been investigated. No phase transformation is detected in the as-cast/rolled specimen. However,the structural stability of the glass against plastic deformation is worse after pre-annealing,indicated by nanocrystallization in preannealed/rolled specimens with large deformation degrees. Moreover,with increasing deformation degree,the free-volume content in a pre-annealed/rolled specimen increases at a lower average rate than that in an as-cast/rolled specimen. | ZHOU Wei LU BinFeng KONG LingTi LI JinFu ZHOU YaoHe | 2011 | Chinese Science Bulletin2011，56，36： | 3 |

| 18 | Entropy as a selection rule for crystal growth in undercooled binary eutectic melts显示文摘A solution entropy model was developed for the undercooled binary eutectic alloy systems. As an ex-tension of Taylor and Fidler et al.'s model, the present model considered the change of phase compo-sition with the increase of undercooling. Furthermore, the sub-regular solution model and the interac-tion parameter (IAB) were also introduced. In this paper, the extended model is used to calculate the solution entropy for binary eutectic phases under the undercooled condition, and the application scope of the model is also extended. Not only the growth manner of eutectic phases, but also the transition of morphologies may be predicted and explained by calculating the solution entropy of eutectic phases under the non-equilibrium condition with the developed model. Experimental results show that the developed model is valid for the undercooled Ni-Si and Ni-Sn eutectic alloy systems. | LU YiPing XI ZengZhe YANG GenCang LIN Xin ZHOU YaoHe | 2009 | Chinese Science Bulletin2009，54，6： | 2 |

| 20 | GRAIN REFINEMENT IN BULK UNDERCOOLED Ni-BASED ALLOY显示文摘Fluxing of 5 g bulk melt Ni77Si13B10 permits high undercoolings to be attained prior to nu-cleation onset.Investigations of grain refinement in the bulk undercooled alloy as a function ofundercooling,recalescence behavior and cooling rate have been reported.A significant inhomo-geneity of reduction in grain size of a bulk sample is observed,which is caused by the different so-lidification conditions:(1)recalescence process,and(2)the followed plateau in which the heatrelease and extraction rates are equal.It is concluded that the homogeneous refined microstructurecan be achieved if the initial undercooling prior to nucleation,or cooling rate after recalescence isfurther increased. | Li,Delin Yang,Gencang Zhou,Yaohe Northwestern Polytechnical University,Xi’an 710072,China | 1993 | 中国有色金属学会会刊:英文版1993，3，4： | 2 |
