摘要
利用金相显微镜、扫描电镜和万能电子材料试验机对马氏体时效钢铸件的组织和力学性能进行了考察。结果表明,马氏体时效钢铸件热处理后强度较高,受制于其内部铸造缺陷。
The microstructure and mechanical properties of 18Ni maraging steel cast were investigated by means of optical microscope and scanning electron microscope as well as universal electric material testing machine. It was shown that the maraging steel cast exhibited a higher strength, which was controlled by the casting defects in it.
