| 4 | Effect of heat treatment on LPSO morphology and mechanical properties of Mg-Zn-Y-Gd alloys显示文摘The mechanical properties and microstructure were investigated under different Zn content and heat treatment conditions in a Mg-Zn-YGd cast alloy.A part of the long period stacking order(LPSO)phases transformed to W-M^ZnaRE?phases with an increase in Zn content from 0.9 at.%to 1.8 at.%,and the ultimate tensile strength(UTS)increased from 229 MPa to 248 MPa.With solution treatment at 480°C,the content of the LPSO phase and strength sharply decreased in the Mg-1.8Zn-0.8Y-0.8Gd alloy,whereas this change was not significantly observed in the Mg-0.9Zn-O.8Y-O.8Gd alloy.After solution treatment,the elongation significantly improved and the UTS sharply decreased in both alloys.The lamellar and filminess LPSO phases were observed with aging treatment at 200℃.Moreover,the strengthening efficiency of lamellar and filminess LPSO phases was lower than that of the block LPSO phases.Therefore,the UTS of the T6 state was lower than that of the as-cast alloy. | Hongxin Liao Jonghyun Kim Taekyung Lee Jiangfeng Song Jian Peng Bin Jiang Fusheng Pan | 2020 | Journal of Magnesium and Alloys2020，8，4： | 14 |
| 5 | A review on hot tearing of magnesium alloys显示文摘Hot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products.Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood,it is of great importance to investigate the hot tearing behaviour of magnesium alloys.This review attempts to summarize the investigations on hot tearing of magnesium alloys over the past decades.The hot tearing criteria including recently developed Kou’s criterion are summarized and compared.The numeric simulation and assessing methods of hot tearing,factors influencing hot tearing,and hot tearing susceptibility(HTS)of magnesium alloys are discussed. | Jiangfeng Song Fusheng Pan Bin Jiang Andrej Atrens Ming-Xing Zhang Yun Lu | 2016 | Journal of Magnesium and Alloys2016，4，3： | 12 |
| 6 | Clarifying the roles of grain boundary and grain orientation on the corrosion and discharge processes of α-Mg based Mg-Li alloys for primary Mg-air batteries显示文摘The corrosion behavior at open circuit potential(OCP)and discharge properties under applied anodic currents of twoα-Mg based Mg-Li alloys,i.e.,LAZ131 and LAZ531,with different microstructural features for primary Mg-air batteries are investigated.The results show that the grain boundaries contribute equally to the corrosion and discharge processes,which are attacked preferentially than the grain interiors and accelerate the dissolution processes ofα-Mg based Mg-Li alloys.The(10-10)/(11-20)orientated grains are attacked preferentially than the(0002)orientated grains on the corrosion and discharge process.The increased corrosion rate and improved discharge properties are attributed to the refinement of grain size,decreased content of(0002)orientated grains and increased content of(10-10)/(11-20)orientated grains.Of those,the LAZ531 alloy possesses high and steady discharge voltage at small discharge current density for long time,with the values of 1.4801 V at 2.5 mA cm^(-2)and 1.3742 V at 10 mA cm^(-2). | Huabao Yang Liang Wu Bin Jiang Wenjun Liu Jiangfeng Song Guangsheng Huang Dingfei Zhang Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，3： | 9 |

| 8 | Innovative endoscopic enucleations of the prostate--Xie’s Prostate Enucleations显示文摘In the past 2 decades,endoscopic enucleation of the prostate has become a safe and effective surgical treatment for benign prostatic hyperplasia(BPH),with comparable outcomes to traditional surgeries.Transurethral vapor enucleation and resection of the prostate(TVERP),transurethral vapor enucleation of the prostate(TVEP),and ultrasound-navigated TVEP(US-TVEP)are new,innovative endoscopic enucleation procedures.These procedures are named Xie’s Prostate Enucleations(Xie’s Procedures for short).Current clinical data indicate that Xie’s Procedures are safe and effective treatment options for patients with BPH,especially for patients with larger prostates.Further prospective,randomized clinical trials compared with traditional transurethral resection of prostate(TURP)are still needed. | Liping Xie Xiao Wang Hong Chen Xiangyi Zheng Ben Liu Shiqi Li Yeqing Mao Qiqi Mao Song Wang Jiangfeng Li Tillmann Loch | 2018 | Asian Journal of Urology2018，5，1： | 6 |
| 9 | Determination of full-scale pore size distribution of Gaomiaozi bentonite and its permeability prediction显示文摘Gaomiaozi(GMZ)bentonite is a potential buffer/backfill material for a deep geological disposal of highlevel radioactive waste.It has a wide pore size distribution(PSD)with sizes ranging from several nanometers to more than one hundred microns.Thus,properly characterizing the pore structures of GMZ bentonite is a challenging issue.In this study,pressure-controlled porosimetry(PCP),ratecontrolled porosimetry(RCP),and scanning electron microscopy(SEM)were used to investigate the PSD of GMZ bentonite,The results indicate that each method has its limitation,and a combined use of PCP and RCP is suitable to obtain the full-scale PSD of GMZ bentonite.Moreover,we also compared the full-scale PSD with nuclear magnetic resonance(NMR)result.It is found that there is no significant difference in the range of PSD characterization between NMR and mercury intrusion method(PCP and RCP).However,in a ce rtain range,the detection accuracy of NMR is higher than that of mercury injection method.Finally,permeability prediction based on PCP and SEM data was conducted,and both of the two methods were found to be able to predict the permeability.The combined method is effective to obtain the full-scale PSD of GMZ bentonite,which is the key to estimation of the sealing ability of bentonite buffer. | Jiangfeng Liu Shuaibing Song Xulou Cao Qingbin Meng Hai Pu Yangguang Wang Jianfeng Liu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 5 |
| 10 | High-temperature mechanical properties of as-extruded AZ80 magnesium alloy at different strain rates显示文摘The mechanical properties of as-extruded AZ80 magnesium alloy at temperatures of 450-525℃ and strain rates of 3.0 s^(−1)and 0.15 s^(−1)were investigated by tensile tests.Zero ductility of alloy appeared at 500℃ with a strain rate of 0.15 s^(−1),while the zero strength and zero ductility of the alloy were obtained nearly simultaneously at 525℃ with a strain rate of 3.0 s^(−1).The results indicated that the lower strain rate accelerated the arrival of zero ductility.As the temperature increased,the failure mode of the alloy developed from trans-granular fracture to cleavage fracture and then to inter-granular fracture with the feature of sugar-like grains and fusion traces.The existence of the low-melting composite ofβ-Mg_(17)Al_(12) and Al_(8)Mn_(5) particles segregated near the Mg_(17)Al_(12) phase along grain boundaries were demonstrated to be the reason for the brittle fracturing of the AZ80 alloy at high temperatures.Furthermore,microstructural evolution at temperatures approaching the solidus temperature was discussed to clarify magnesium alloy’s high temperature deformation mechanism. | Wenjun Liu Bin Jiang Hongchen Xiang Qing Ye Shengqi Xia Siqiang Chen Jiangfeng Song Yanlong Ma Mingbo Yang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，7： | 3 |
| 11 | Microstructures and mechanical properties of titanium-reinforced magnesium matrix composites: Review and perspective显示文摘Currently, many gratifying signs of progress have been made in magnesium(Mg) matrix composites(MMCs) by virtue of their high mechanical properties both at room and elevated temperatures. Although the commonly used reinforcements in MMCs are ceramic particles,they often provide improved yield and ultimate stresses by a significant loss in ductility. Therefore, hard metallic phases were introduced as alternative candidates for the manufacturing of MMCs, especially titanium(Ti). It has a high melting point, high Young’s modulus, high plasticity, low level of mutual solubility with Mg matrix, and closer thermal expansion coefficient to that of Mg metal than that of ceramic particles. It is highly preferable to provide both high ultimate stress and ductility in Mg matrix. However, many critical challenges for the fabrication of Ti-reinforced MMCs remain, such as Ti’s homogeneity, low recovery rate, and the optimization of interfacial bonding strength between Mg and Ti, etc. Meanwhile, different fabrication methods have various effects on the microstructures, mechanical properties, and the interfacial strength of Ti-reinforced MMCs. Hence, this review placed emphasis on the microstructural characteristics and mechanical properties of Ti-reinforced MMCs fabricated by different techniques. The influencing factors that govern the strengthening mechanisms were systematically compared and discussed. Future research trends, key issues, and prospects were also proposed to develop Ti-reinforced MMCs. | Hong Yang Xianhua Chen Guangsheng Huang Jiangfeng Song Jia She Jun Tan Kaihong Zheng Yiming Jin Bin Jiang Fusheng Pan | 2022 | Journal of Magnesium and Alloys2022，10，9： | 2 |

| 14 | Pulse-width-induced polarization enhancement of optically pumped N-V electron spin in diamond显示文摘The nitrogen-vacancy(N-V)center in diamond is a widely used platform for quantum information processing and sensing.The electron-spin state of the N-V center could be initialized,read out optically,and manipulated by resonate microwave fields.In this work,we analyze the dependence of electron-spin initialization on widths of laser pulses.We build a numerical model to simulate this process and to verify the simulation results in experiments.Both simulations and experiments reveal that shorter laser pulses are helpful to the electron-spin polarization.We therefore propose to use extremely short laser pulses for electron-spin initialization.In this new scheme,the spin-state contrast could be improved about 10%in experiments by using laser pulses as short as 4 ns in width.Furthermore,we provide a mechanism to explain this effect,which is due to the occupation time in the meta-stable spin-singlet states of the N-V center.Our new scheme is applicable in a broad range of N-V-based applications in the future. | YUMENG SONG YU TIAN ZHIYI HU FEIFEI ZHOU TENGTENG XING DAWEI LU BING CHEN YA WANG NANYANG XU JIANGFENG DU | 2020 | Photonics Research2020，8，8： | 1 |

| 17 | Optimized Tension for AZ31B Thin Sheets Rolled with On-Line Heating Rolling显示文摘On-line heating rolling mill which could efficiently preheat sheet and apply tensile force on both ends of the sheet along rolling direction(RD)was used to investigate the effect of tension on mechanical behavior and shape quality of magnesium sheets.For revealing the infl uence mechanism,many analysis techniques including optical microscope,electron backscattered diffraction,macrotexture and transmission electron microscope were performed.The shape defect,edge wave,could be eliminated under higher tension along RD,which was attributed to more uniform distribution of microstructure and microstrain.Nevertheless,it is undesirable that the forward tensile force exceeds 3 kN in present work because the strength decreased for high recrystallization level when the tensile force is beyond this value.Furthermore,the main deformation mode was still slip during rolling process despite of accompanying twining,e.g.,double twins,but more prismatic slip activated when tensile force exceeds 3 kN.The distribution of shear bands was affected by the applied tensile force that they appear as'V'shape along RD at a low forward or backward tensile force,while they appear as reticulate shape under applied tensile force of 5 kN. | Biquan Xiao Jiangfeng Song Hua Zhao Aitao Tang Qiang Liu Bin Jiang Shitao Dou Fusheng Pan | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，2： | 1 |

| 20 | Effect of Zener–Hollomon Parameter on High-Temperature Deformation Behaviors of Mg–6Zn–1.5Y–0.5Ce–0.4Zr Alloy显示文摘High-temperature compressive deformation behaviors of Mg–6Zn–1.5Y–0.5Ce–0.4Zr alloy were investigated at temperatures and strain rates ranging from 523 to 673 K and from 0.001 to 1 s~(-1),respectively.The studied alloy was mainly composed ofα-Mg,Mg_(3)Zn_(6)Y(I phase),Mg–Zn–Ce and Mg_(3)Zn_(3)Y_(2)(W phase).The constitutive equation of Mg alloy was obtained,and the apparent activation energy(Q)was determined as 200.44 k J/mol,indicating that rare earth phase increases the difficulty of deformation.The work hardening involves three stages:(1)linear hardening stage;(2)strain hardening stage;and(3)softening and steady-state stage.During these three stages,the dislocation aggregation and tangling,dynamic recovery and recrystallization occur sequentially.To characterize the dynamic recrystallization(DRX)volume fraction,the DRX kinetics was investigated using the Avrami-type equation.The deformation mechanism of magnesium alloy under different Zener–Hollomon parameter(Z)value conditions was also studied.At high Z values and intermediate conditions,dislocations rapidly generate and pile up in the alloy.Recrystallization is hardly seen at this time.At low Z condition,the DRX occurs in the alloy. | Bo Wu Jianbo Li Lizi Liu Xianhua Chen Jun Tan Jiangfeng Song Muhammad Rashad Fusheng Pan | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，5： | 1 |
