| 摘 要： | 利用ET2G型红外测温仪测定了试样的冷却曲线，并利用光学显微镜、扫描电镜以及力学性能试验设备对不同形态的H13钢贝氏体组织和力学性能进行了研究。结果表明，在等温条件下，随等温时间的延长、贝氏体含量增加，低温等温时的增加量远大于高温等温时的增加量；马氏体与马氏体有一最佳比例，此时复相组织的力学性能最好。

| Abstract: | The cooling curve of H13 steel sample in air was gotten by infrared thermoscope.And the different microstructures of bainite and the mechanical properties were studied by means of optical microscopy,SEM,and mechanical properties test equipment.The results show that there is more bainite if prolonging the isothermal time and the bainite increases more rapidly at lower isothermal temperature.An appropriate proportion of martensite and bainite in the combined phases can offer the best mechanical properties. |
