| Abstract: | The effect of vacuum quenching temperature, quenching oil temperature and vacuum degree of cooling chamber on the microstructure and mechanical properties of 5CrMnMo steel was studied by means of hardness testing, metallographic examination and impact testing. The effect of common tempering process on the hardness and impact toughenss of 5CrMnMo steel was also investigated. The effect of vacuum quenching on the heat treatment distortion of 5CrMnMo steel was studied through the measurement of radial jitter of the specimen before and after both vacuum and common heat treatment. |
