本文建立了一种晶面—晶向投影图,以揭示体心立方晶体{100)、{110)和{112)晶面簇中诸晶面以及在这些晶面上各重要晶向。根据该投影图,可以方便地获得这些晶面和晶向的位向关系,并全面确定在这些晶面上可能出现的全位错的反应类型及其具体组合方式。 In this paper, a crystal plane-crystallographic projection is established to reveal the crystal planes in the {100}, {110} and {112} planes of body-centered cubic crystals and the important crystal orientation on these planes. Based on this projection, the orientation of these planes and orientations can be conveniently obtained and the types of all-dislocations that can occur on these planes and their specific combinations can be fully determined.
