Abstract

Abstract

The measurement of the value and distribution for micro-residual stress in materials was crucial and difficult for micro-fracture theory.A regular Vickers micro-indentation for evaluating the micro-residual stress in micron-range was introduced.Three common metals including mild steel,copper and aluminum alloy were used in the experiment,and residual stresses were induced “in-situ” by using three-point bending.The results show that the present measurement is accurate.
- residual stress,
- micro-hardness,
- indentation,
- bending
