摘要：

An in depth analysis on twin variant selection and twin growth character during compression by means of "interrupted in situ'' EBSD orientation measurement was carried out. An experimental verification and geometrical analysis of the use of Schmid's law as a criterion for selecting twin variants was performed, and proved to be conclusive. Twin variants having Schmid factors higher than 0.4 have a good chance to be activated. The twin growth exhibits two modes: {11-22} twins show a tendency to multiple variants system (MVS) and {10-12} twins show predominant variant system (PVS). The Schmid factor plays an important role in MVS and PVS.
