Abstract:
The effect of residual stress forming during sholling peening and rolling was discussed. In this paper, we proved that attenuation of residual compression stress was
relating to the compression yield limit +_(s).(c) and +_(s).(t) of materials, and pressent that if effect of surface deformation hardening is judged by fatigue strength
change rate Delta +_(h)/+_(h), +_(b)(o)/+_(s)(c) may be regarding as a criterion. The larger +_(b)(o)/+_(s)(c) is, the better the surface hardening effect upon the
materials is. So it is convenient to select materials for shot-peening and rolling hardening by the date of static compression behaviour of materials, which is practically
valuable.
