Webnegative Schmid factors (SFs). The variant selection of them are interpreted in terms of shear accommodations. The observed twin variants require the least or no accommodation through deformation modes with high CRSSs, but the most or more accommodation through those with low CRSSs. 1. Introduction WebThe analysis of slip in h.c.p. crystals can be demonstrated by considering the special case in which the slip direction, the tensile axis and the normal of the slip plane are all coplanar. ... shown in the diagram below, it is apparent that the primary slip system (i.e. the system with the greatest Schmid factor) in h.c.p. crystals will be [010 ...
Webplane that possesses the highest Schmid factor in between the {11 0} planes of the [111] zone. On the other hand, for !/CRSS<-0.4 the slip was preferred on another {11 0} plane of the [111] zone, specifically either on the (01 1) or on the (1 10) plane. The reason for this change of the slip plane can be understood by following the ...
