Abstract

In this study, the author formulated the isothermal transformation curve of Ni-Cr structural steel by the microvickers and microstructure, and examined the relation between the heat-treatment of austempering and hardness value, tortional strength, Charpy impact value and microstructure test at room and high temperatures.
