摘要: 用传统铸造和喷射成形工艺制备了H13钢,然后再进行锻造加工,利用光学金相显微镜(OM)、扫描电子显微镜(SEM)、X射线衍射分析(XRD)等分析方法及硬度测试对不同工艺制备的H13钢的显微组织和硬度进行分析.研究结果表明,喷射成形及其锻造加工的H13钢的组织及硬度明显的优于传统工艺制备的H13钢.Abstract: H13 steel was prepared by traditional processes and spray forming respectively, then it was subjected to forging processes. The miorostructure and hardness of H13 steel prepared by different processes were studied by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and hardness tester. The results show that the spray formed and forged H13 steel possesses a finer grain size and a higher hardness than traditional H13 steel.
