The surface worked type 304 stainless steel exhibits an extraordinary behavior when subjected random fatigue load. In this study the effect of load history on the cumulative damage was examined. The random loads are 1) two step increasing stresses, 2) two step decreasing stresses, 3) repeated high and low step stresses, 4) repeated low and high step stresses, and 5) gradually increasing stresses. In any cases the cumulative damage calculated according to Miner’s rule remarkably exceeded 1.0, especialy for the gradually increasing stresses. In order to survey the mechanism, the elastic and plastic strain behaviors were studied. The extraordinal cumulative fatigue damage could be explained by the remarkable fatigue hardening behavir of austenitic stainless steel.

Type 304 Stainless Steel

Application of microforming in various research areas has received much attention due to the increased demand for miniature metallic parts that require mass production. For the accurate analysis and design of microforming process, proper modeling of material behavior at the micro/meso-scale is necessary by considering the size effects. Two size effects are known to exist in metallic materials. One is the “grain size” effect, and the other is the “feature/specimen size” effect. This study investigated the “feature/specimen size” effect and introduced a scaling model which combined both feature/specimen and grain size effects. Predicted size effects were compared with experiments obtained from previous research and showed a very good agreement. The model was also applied to forming of micro-features by coining. A flow stress model for Type 304 stainless steel taking into consideration the effect of the grain and feature size was developed and implemented into a finite element simulation tool for an accurate numerical analysis. The scaling model offered a simple way to model the size effect down to length scales of a couple of grains and extended the use of continuum plasticity theories to micro/meso-length scales.
