摘要
研究了回火温度和时间对 4 0 Cr3Mo V钢力学性能的影响。同回火时间相比 ,回火温度对力学性能的作用要显著得多。在 5 5 0℃以下回火时 ,力学性能随回火温度的提高变化缓慢 ;当回火温度高于 5 80℃时 ,随回火温度的提高 ,强度急剧下降 ,韧性迅速增加。
Abstract:The effect of tempering temperature and tempering time on the mechanical properties of 40Cr3MoV steel has been studied. Comparing to tempering time, tempering temperature has stronger effect on the mechanical properties. Below 550 ℃, the mechanical properties change slightly with the increase of temperature; above 580 ℃, the strength drops and the toughness increases rapidly with the increase of temperature.
