| 摘 要： | 采用透射电子显微分析的方法 ,研究了H13钢不同回火温度下组织和性能之间的关系。结果表明 :H13钢在 30 0℃～ 6 30℃温度范围内回火 ,显微组织经历了由回火马氏体组织向回火托氏体组织的转变过程 ,在 5 2 0℃左右出现二次硬化峰。但在二次硬化峰出现时没有发现合金碳化物相的析出。

| Abstract: | The relationships between the microstucture and the mechanical properties of the H13 steel under different tempering temperature have been studied by means of optical microscope and TEM observations. The results show that the microstructure transforms from temper martensite to temper troostite when the temper temperature is from 300℃ to 630℃,and the peak of secondary hardening appears at about 520℃.There are no alloy-carbide precipitates at the peak of secondary hardening. |

| Keywords: | H13 steel temper secondary hardening alloy-carbide |
