采用光学显微分析和透射电子显微分析的方法，研究了H13钢在不同回火温度下其组织和性能的关系.结果表明，H13钢在300～630 ℃范围内回火，其显微组织经历了由回火马氏体组织向回火屈氏组织的转变过程，二次硬化出现时没有合金碳化物相析出.

The microstructure and the mechanical properties of H13 steel tempered at various temperatures have been studied by means of the optical microscope and TEM observations.The results show that the microstructure transforms from tempering martensite to tempering troosite in the tempering temperature ranging from 300 ℃ to 630 ℃.There are no alloy-carbide precipitates at the peak of the secondary hardening.
