【Abstract】 After the 40Cr steel is heated in the one-phasic austenite range and the biphasic range and then austempered, the structure analisis of it shows that owing to the different conditions and compositions of austenites, we can obtain different kinds of structures after aus-tempering at equal temperatures, and the transformation ranges of bainite ang martensite will move toward lower temperature.更多还原
