测试了不同温度淬火及回火试样的室温和高温机械性能,所得结果表明:经1050℃淬火,580℃回火处理的试样,具有良好的综合机械性能,断口呈现小单元的准解理平面,有明显的韧窝。
The mechanical properties at room temperature and high temperature of quenched and tempered samples with different temperature were tested. The results show that the samples tempered at 1050 ℃ and tempering at 580 ℃ have good mechanical properties and the quasi-cleavage of the small unit Plane, obvious dimples.
