【摘要】 为满足轻合金等温精密成形模具的工作条件要求,通过合理选择综合性能符合要求的模具材料H13钢,采用不同的热处理工艺对试样进行退火、淬火、回火试验,测试其硬度、冲击韧性,并观察金相组织,作为H13钢模具工艺优选的依据。试验结果表明H13钢在最佳完全退火温度、淬火温度、回火温度下可得到最优综合性能。更多还原

【Abstract】 In order to meet the requirements of light alloy ausforming die,by choosing H13 steel die materials rationally,different heat treatment processes such as annealing,quenching and tempering are applied to samples.The hardness,shock toughness and metallographic structure will be chosen as the basis for H13 steel die process.The test results show that the surface of H13 steel can obtain the optimum performance at temperature of complete annealing,quenching and tempering.更多还原
