Plastic behavior of 304 stainless steel for complex loading at high temperature

The structural components used at high temperature are subjected to the severe condition of combining complex loading and temperature history. For the strength design of such components, it is necessary to investigate the deformation behavior of materials used at high temperature. The high temperature deformation is correlated with loading condition and temperature state in complicated manner. Experimental investigations on the high temperature deformation are reported by several researchers. The results are summarized by the authors (Ikegami and Niitsu 1985b). Extensive and systematic experiments are necessary to understand the high temperature deformation. The authors continue experimental works on the plastic deformation at high temperature and report the results in the papers listed in the reference. This paper presents some characteristic behavior of metal at high temperature on the basis of the authors' experimental results. (orig.)
