| Abstract: | The spheroidizing process of Cr5 high-carbon-chromium hypereutectoid steel was investigated to determine appropriate the spheroidizing temperature and the duration at temperature.The results show that the spheroidizing temperatures suitable for Cr5 steel are 820 to 840 ℃ at which after spheroidizing the microstructure will consist of ferrite matrix and dispersed Cr23C6,Cr7C3 and Fe3C carbides. |
