摘要
The microstraining prior to yield of several common metallic materials has been studied.The resistances of metals to microstrain and to macroyield are believed to be based on different deformation mechanisms and to be changed in different patterns.The influential factors upon the microstraining,such as heat treatment,prestrain,strain-aging and residual stress together with their mechanisms have been also discussed.
