摘要:
提出一种易于理解且严谨的论述,从原理上解释面心和体心立方晶体中快速判断始滑移系的映像规则.首先,将Schmid因子转化成关于夹角φ+λ和φ-λ的余弦函数.该余弦函数在标准投影图上可描述为“力轴靠近滑移系平面”的程度和“夹角φ和λ接近”的程度,以此为判据可快速地比较Schmid因子的相对大小.然后,以数学运算证明映像规则的科学性.
Abstract:
An easy to grasp as well as rigorous discussion is presented to describe the mechanism of the method of mirror image, which is applied to determine the initial glide systems of face-centered and body-centered cubic crystal. Firstly, Schmid factors is transformed into formula of the cosine function of angle φ+λ and φ-λ. This function can be on standard stereographic projection: the closeness of stress to glide-system plane, and the closeness of angle φ and λ. Based on this criterion, the comparison of Schmid factors is easily made. Furthermore, a mathematical demonstration is presented to prove the mirror image method.
