| Abstract: | 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. |
