| Abstract: | This paper have investigated the structure and property changes of 30Cr2MoV steel and 28CrNiMo1V steel during aging by means of optical microscope, scanning electron microscope and X ray diffractometer. The experimental results show that prolonged exposure at elevated temperature leads to materials softening and microstructure changes in grains and along grain boundaries. These changes affect the rotor life. The paper also points out that the properties of 28CrNiMo1V steel is superior to that of 30Cr2MoV steel. |
