| 1 | 利用取向成像研究镁合金的孪生过程显示文摘利用背散射电子衍射取向成像技术,定量分析了具有初始织构的AZ31镁合金平面应变压缩时的孪生过程。结果表明:初始织构为晶粒单胞的c轴平行于轧向时,晶粒内部的{1012}孪生是主要的形变机制,产生(0001)∥轧面的基面织构。随形变量的加大及孪晶的增多,86.3°〈1120〉的孪晶取向关系先急剧增加,然后明显降低。孪晶量与基面取向晶粒的面积百分数对应,而跟孪晶关系出现的多少不相对应。测定了应变量与孪晶量的定量关系,并讨论了可能出现的误差。 | 胡轶嵩 杨平 赵祖德 马端骋 | 2004 | 中国有色金属学报2004，14，1： | 11 |
| 2 | 稀土镁合金高温形变孪生变体的选择规律显示文摘研究了高温条件下Mg-Gd-Y-Zr合金形变孪生变体的选择规律。在350℃及真应变为0.05时通过单向压缩铸态Mg-Gd-Y-Zr合金试样,获得形变孪生组织。利用背散射电子衍射(EBSD)技术与透射电子显微镜(TEM)确定孪生类型为{1012}孪生。通过对比EBSD测试结果与理论计算结果,确定了孪生变体。采用Schmid因子准则与Taylor准则分析了{1012}孪生发生的规律。结果表明:Schmid因子准则仅仅考虑孪生变体的Schmid因子,其预测结果与实验结果不符;而Taylor准则考虑了孪生、基面滑移与非基面滑移的相互协调作用,可准确预测{1012}孪生的变体选择结果;稀土镁合金的高温形变也需要孪生参与协调塑性变形。 | 张新明 李理 邓运来 唐昌平 赵一生 | 2009 | 中国有色金属学报2009，19，6： | 2 |
| 3 | Shear bands in magnesium alloy AZ31显示文摘During deformation of magnesium at low temperatures, cracks always develop at shear bands. The origin of the shear bands is the {101-1} twinning in basal-oriented grains and the mobility of this type of twin boundary is rather low. The most frequent deformation mechanisms in magnesium at low temperature are basal slip and ({101-2}) twinning, all leading to the basal texture and therefore the formation of shear bands with subsequent fracture. The investigation on the influences of initial textures and grain sizes reveals that a strong prismatic initial texture of 〈0001〉 parallels to TD and fine grains of less than 5 μm can restrict the formation and expansion of shear bands effectively and therefore improve the mechanical properties and formability of magnesium. | 杨平 毛卫民 任学平 唐全波 | 2004 | 中国有色金属学会会刊:英文版2004，14，5： | 0 |
| 4 | Influence of initial textures on dynamic recrystallization and textures in AZ31 magnesium alloys显示文摘Microscopy and X ray diffractometry were applied to inspect the influence of initial texture on dynamic recrystallization and texture formation in AZ31 magnesium alloys during channel die compression. The results show that stress-strain curves, microstructures and textures depend on initial textures. Two types of nucleation sites are detected which are in different proportions depending on initial textures. Dynamic recrystallization proceeds faster in samples with more inhomogeneity. When the basal planes of grains are parallel to rolling plane of sample with scattering around transverse direction, no new texture component occurs and texture is strengthened together with dynamic recrystallization. By other initial textures there are texture changes during hot deformation. New grains rotate gradually to basal orientation at heavy strain. | 杨平 崔凤娥 马世才 G Gottstein | 2003 | 中国有色金属学会会刊:英文版2003，13，3： | 0 |
