摘　　要：将热等静压技术应用于ZG0Cr14Ni5Mo2Cu铸件,分别测试了铸件经热等静压处理前后的尺寸、室温力学性能及处理前后铸件的X射线检测底片、金相组织和冲击试块断口形貌。试验结果表明:与未经热等静压处理相比,该材料经热等静压处理后,在X射线底片上可显示完全消除了疏松类缺陷,气孔有部分弥合,同时细化了晶粒组织,改善了材料的力学性能。Hot isostatic pressing technology was applied to ZG0Cr14Ni5Mo2Cu castings.The size and mechanical properties of the castings before and after hot isostatic pressing treatment,as well as the X-ray detection film,metallographic microstructure and impact test block fracture morphology were respectively tested.The test results showed that compared with the material without hot isostatic pressing treatment,the material with hot isostatic pressing treatment completely eliminated theporosity defects on the X-ray film,and the gas holes were partially closed.At the same time,the grain microstructure was refined,and the mechanical properties of the material were improved.
