RESISTANCE OF METALS TO MICROSTRAIN AND ITS INFLUENTIAL FACTORS
|
Abstract:
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.
