【摘要】 在系统分析了bcc金属{110}〈111〉,{112}〈111〉和{123}〈111〉多滑移时的单晶屈服面(SCYS)的基础上, 导出了临界剪切应力(CRSS)相等情况下完备的单晶混合屈服应力状态,求出了相应的活化滑移系及5个独立活化滑移系的组合 数,并将所有可能的屈服顶点按晶体结构的对称性加以分类和列表.更多还原

【Abstract】 The single crystal yield surfaces (SCYS) in bcc metals for {110}<111>, {112}<111> and {123}<111> multiple slip were analyzed systematically. The complete yield stress states, the corresponding active systems and the combination number of five independent active systems associated with the particular vertex have been derived under the same critical resolved shear stresses (CRSS’s). All possible yield stresses are classified and listed according to the symmetry of crystal structure.更多还原
