- 論文の詳細を見る
The residual stresses in several tool steels and high carbon-high manganese steels subjected to oil quenching, water quenching, air cooling and each further subzero quenching were measured by Heyn's method. The effects of subzero quenching and of specimen size on the residual stress were studied with tool steels. The change in stresses is rather small by subzero quenching, while the residual stress in surface increases with increasing specimen size. The relation between the residual stress and the amount of martensite was examined with high carbon-high manganese steel Ms temperature of which was 28〜-196℃. The residual stress in surface layer is converted from compression to tension by 15~20% transformation of martensite, particularly when water-quenched and then subzero-quenched.
