| 1 | Recent research and developments on wrought magnesium alloys显示文摘Wrought magnesium alloys attract special interests as lightweight structural material due to their homogeneous microstructure and enhanced mechanical properties compared to as-cast alloys.In this contribution,recent research and developments on wrought magnesium alloys are reviewed from the viewpoint of the alloy design,focusing on Mg-Al,Mg-Zn and Mg-rare earth(RE)systems.The effects of different alloying elements on the microstructure and mechanical properties are described considering their strengthening mechanisms,e.g.grain refinement,precipitation and texture hardening effect.Finally,the new alloy design and also the future research of wrought magnesium alloys to improve their mechanical properties are discussed. | Sihang You Yuanding Huang Karl Ulrich Kainer Norbert Hort | 2017 | Journal of Magnesium and Alloys2017，5，3： | 43 |
| 2 | Role of multi-microalloying by rare earth elements in ductilization of magnesium alloys显示文摘The present work investigates the influences of microalloying with rare earths on the mechanical properties of magnesium alloys.The amount of each rare earth element is controlled below 0.4 wt.%in order not to increase the cost of alloy largely.The synergic effects from the multi-microalloying with rare earths on the mechanical properties are explored.The obtained results show that the as-cast magnesium alloys multi-microalloying with rare earths possesses a quite high ductility with a tensile strain up to 25-30%at room temperature.Moreover,these alloys exhibit much better corrosion resistance than AZ31 alloy.The preliminary in situ neutron diffractions on the deformation of these alloys indicate that the multi-microalloying with rare earths seems to be beneficial for the activation of more slip systems.The deformation becomes more homogeneous and the resultant textures after deformation are weakened. | Yuanding Huang Weimin Gan Karl Ulrich Kainer Norbert Hort | 2014 | Journal of Magnesium and Alloys2014，2，1： | 19 |
| 3 | Dynamic tensile properties and microstructural evolution of extruded EW75 magnesium alloy at high strain rates显示文摘The dynamic tensile properties and microstructural evolution of an extruded EW75 magnesium alloy deformed at ambient temperature and different high strain rates(from 1000 to 3000 s^(-1))along extrusion direction(ED)were investigated by Split Hopkinson Tension Bar(SHTB).The corresponding deformation mechanisms,texture evolution and microstructure changes were analyzed by optical microscope(OM),electron backscatter diffraction(EBSD)and transmission electron microscope(TEM).The results show that the extruded EW75 magnesium alloy along ED exhibits a conventional positive strain rate sensitivity that the dynamic flow stresses increase with in creasing strain rate.Texture measurements show that after dynamic tension,the initial weak texture of extruded EW75 magnesium alloy tansforms to a relatively strong<10-10>//ED texture with increasing strain rates.The microstructural analysis demonstrates that dislocation motion are main deformatin mode to accommodate dynamic tensile deformation at high strain rates.In addition,the interactions of dislocation-dislocation and dislocation-second phase lead to the in crease of flow stress and strain hardening with increasing strain rate. | Jincheng Yu Bo Song Dabiao Xia Xun Zeng Yuanding Huang Norbert Hort Pingli Mao Zheng Liu | 2020 | Journal of Magnesium and Alloys2020，8，3： | 7 |
| 4 | Effects of samarium content on microstructure and mechanical properties of Mg–0.5Zn–0.5Zr alloy显示文摘Effects of samarium (Sm) content (0, 2.0, 3.5, 5.0, 6.5 wt%) on microstructure and mechanical proper-ties of Mg-0.5Zn-0.5 Zr alloy under as-cast and as-extruded states were thoroughly investigated. Results indicate that grains of the as-cast alloys are gradually refined as Sm content increases. The dominant intermetallic ph^se changes from Mg3Sm to Mg4iSm5 till Sm content exceeds 5.0 wt%. The dynami-cally precipitated intermetallic phase during hot-extrusion in dll Sm-containing alloys is Mg3Sm. The intermetallic particles induced by Sm addition could act as heterogeneous nucleation sites for dynamic recrystallization during hot extrusion. They promoted dynamic recrystallization via the particle stim-ulated nucleation mechanism, and resulted in weakening the basal texture in the as-extruded alloys. Sm addition can significantly enhance the strength of the as-extruded Mg-0.5Zn-0.5Zr alloy at room temperature, with the optimal dosage of 3.5 wt%. The optimal yield strength (YS) and ultimate tensile strength (UTS) are 368 MPa and 383 MPa, which were enhanced by approximately 23.1% and 20.8% com-pared with the Sm-free alloy, respectively. Based on microstructural analysis, the dominant strengthening mechanisms are revealed to be grain boundary strengthening and dispersion strengthening. | Kai Guan Fanzhi Meng Pengfei Qin Qiang Yang Dongdong Zhang Baishun Li Wei Sun Shuhui Lv Yuanding Huang Norbert Hort Jian Meng | 2019 | Journal of Materials Science & Technology2019，35，7： | 4 |
| 5 | Microstructure and mechanical properties of large-scale Mg-Gd-Y-Zn-Mn alloys prepared through semi-continuous casting显示文摘Large-scale Mg-8Gd-4Y-1Zn-Mn(wt.%)alloy ingot with a diameter of 315 mm and a length of 2410 mm was prepared through semi-continuous casting.Chemical composition,microstructure and mechanical properties at different locations of the samples with as-cast,T4 and T6 heat-treated states,respectively,were investigated.No obvious macro segregation has been detected in the high-quality alloy ingot.The main eutectic structures at all different locations are composed ofα-Mg,Mg3RE-type,Mg5RE-type and LPSO phases.At the edge of ingot,the unusual casting twins including 10-12 extension twins and 10-11 compression twins were observed due to the intensive internal stress.In T4 heat-treated alloy,the micro segregation was eliminated.The remained phases wereα-Mg and LPSO phase.Combined with the remarkable age-hardening response,T6 samples exhibits improved mechanical properties at ambient temperature,which derives from the dense prismaticβ'precipitates and profuse basalγ'precipitates. | Kui Wang Jingfeng Wang Xiaoxu Dou Yuanding Huang Norbert Hort Sarkis Gavras Shijie Liu Yanwu Cai Jinxing Wang Fusheng Pan | 2020 | Journal of Materials Science & Technology2020，52，17： | 4 |
| 6 | Unexpected formation of hydrides in heavy rare earth containing magnesium alloys显示文摘Mg–RE(Dy,Gd,Y)alloys show promising for being developed as biodegradable medical applications.It is found that the hydride REH_(2) could be formed on the surface of samples during their preparations with water cleaning.The amount of formed hydrides in Mg–RE alloys is affected by the content of RE and heat treatments.It increases with the increment of RE content.On the surface of the alloy with T4 treatment the amount of formed hydride REH_(2) is higher.In contrast,the amount of REH2 is lower on the surfaces of as-cast and T6-treated alloys.Their formation mechanism is attributed to the surface reaction of Mg–RE alloys with water.The part of RE in solid solution in Mg matrix plays an important role in influencing the formation of hydrides. | Yuanding Huang Lei Yang Sihang You Weimin Gan Karl Ulrich Kainer Norbert Hort | 2016 | Journal of Magnesium and Alloys2016，4，3： | 3 |
| 7 | Understanding effects of microstructural inhomogeneity on creep response-New approaches to improve the creep resistance in magnesium alloys显示文摘Previous investigations indicate that the creep resistance of magnesium alloys is proportional to the stability of precipitated intermetallic phases at grain boundaries.These stable intermetallic phases were considered to be effective to suppress the deformation by grain boundary sliding,leading to the improvement of creep properties.Based on this point,adding the alloying elements to form the stable intermetallics with high melting point became a popular way to develop the new creep resistant magnesium alloys.The present investigation,however,shows that the creep properties of binary Mg-Sn alloy are still poor even though the addition of Sn possibly results in the precipitation of thermal stable Mg_(2)Sn at grain boundaries.That means other possible mechanisms function to affect the creep response.It is finally found that the poor creep resistance is attributed to the segregation of Sn at dendritic and grain boundaries.Based on this observation,new approaches to improve the creep resistance are suggested for magnesium alloys because most currently magnesium alloys have the commonality with the Mg-Sn alloys. | Yuanding Huang Hajo Dieringa Karl Ulrich Kainer Norbert Hort | 2014 | Journal of Magnesium and Alloys2014，2，2： | 3 |

| 20 | GTA Welds of Iron-Aluminide Based Alloys显示文摘The weldability of two Fe3Al-based intermetallic alloys and one Fe- 16%Al-based (atom fraction) alloy has been investigated for gas tungsten arc (GTA) welding on sheets with a thickness of 2 mm. The results indicated that pre-heating and post-annealing treatment were important procedures for retarding cold crack initiation and the proper selection of filler could effectively improve the weldability. For the same alloys with the same welding filler, it is better to choose lower welding current, in another word, lower heat input. | Dechun Gao, Wangyue Yang, Min Dong, Jihua Huang, Yuanding Huang, Zuqing Sun Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China | 2001 | Journal of University of Science and Technology Beijing2001，8，1： | 1 |
