20113 An evaluation method for strength reusability of parts by ion-implantation

Abstract

The purpose of the present study is to develop a sensor for evaluating the reusability of structural parts under cyclic loading. The basic principle of the sensing is the accelated fatigue damage of the sensor with induced residual stress by ion implanting technique. In the present paper, a new experimental method is proposed for the thin specimen, and the relationship between Fe ion implanting and fatigue damage (crack initiation) is experimentally investigated.
