【Abstract】 In this paper, effect of quenching and tempering temperature on microstrucutures and mechanical properties of SPV490 steel has been studied. According to the microstructures and the phases of the samples and comparing the mechanics properties, the reasonable quenching and tempering schedules have been proposed, that is quenching from 900℃ and tempering between 600 - 620℃.更多还原
