304 Stainless 강의 열처리 싸이클에 따른 조직과 기계적 특성에 관한 연구

Abstract

Several microstructural parameters have been supposed to play a role in controlling mechanical properties of stainless steel. In order to ascertain which of the microstructural parameters plays the major role in controlling the mechanical behavior a series of heat treatment path experiments have been carried out on four stainless in the various addition of Cr and Ni contents. The mechanical properties(tensile strength, hardness, yield strength, elongation, Charpy impact test etc.) have been found to be affected not only by microstructure by heat treatment temperature and time, but also by the contents of Cr and Ni. The temperature nature of solution treatment has also been found to influence the mechanical properties of 304 stainless steels.
