Abstract:
The microstructure in shot-peening surface plastic straining layer of several metals are investigated. It was found that this plastic deformation is not the same as the
simple monotonic plastic deformation. As a result of cyclic plast ic deformation, material in the surface layer is subjected to "cyclic hardening" or "cyclic softening" as
it occurs in the strain
fatigue test. The appearance of cyclic hardening or cyclic softening is dependent on the initial microstructure of the material.
