在电子 backscattering 衍射的 situ 观察,技术被用来评估在奥氏体和马氏体之间的取向关系(为高锰的 -M) 导致转变的粘性钢。这被注意与热马氏体不同,它很好与奥氏体服从了 KS 关系,在有奥氏体的导致变丑的 -M 之间的取向关系在变丑期间变化了,也就是, KS 和 NW 关系共存了。没有清楚的差别以在 -M 变体之间的 martensitic 取向,形状和错误取向二种关系地在 -M 变体之间存在。并且这现象发生在几乎所有奥氏体的谷物,不同取向在这研究调查了。原子排水量机制通过结合建筑群在弄歪的 fcc 格子部分脱臼滑倒在这篇文章被使用解释 KS 和 NW 关系的共存。
In situ observation of electron backscattering diffraction technique was used to evaluate the orientation relationships between austenite and α′-martensite(α′-M) for high manganese transformation-induced plasticity steel.It was noted that different from the thermal martensite,which well obeyed K-S relationship with austenite,the orientation relationship between deformation-induced α′-M with austenite changed during deformation,namely K-S and N-W relations coexisted.No clear differences existed between α′-M variants with two kinds of relationships in terms of martensitic orientation,shape and the misorientation between α′-M variants.And this phenomenon happened in almost all austenitic grains with different orientations investigated in this study.An atom displacement mechanism through conjugate complex slips of partial dislocations in the distorted fcc lattice was applied in this article to interpret the coexistence of K-S and N-W relationships.
