摘要
本文研究了几种常见金属材料屈服前的微应变过程。指出微应变抗力与宏观屈服抗力二者基于不同的形变机制,变化规律也不尽相同。讨论了热处理、预形变、形变时效和残余应力对材料的微应变过程的影响及其机制。
The microstraining prior to yield of several common metallic mate-rials has been studied. The resistances of metals to microstrain and to macroyieldare believed to be based on different deformation mechanisms and to be changedfrom different patterns. The influential factors upon the microstraining, such asheat treatment, predeformation, strain-aging and residual stress together withtheir mechanisms have been also discussed.
