Abstract

The 20CrMnTiH gear steel was heated at temperature range from 850°C to 1250°C and at holding time range from 0s to 480s to obtain the law of austenite grain growth by using Gleeble-3500 thermo-simulation-machine in this research. The effects of heating temperature and holding time on austenite grain growth behavior were investigated. The results show that austenite grain size increased with the increase of heating temperature and the extension of holding time. By introducing the Sellars model, the austenite grain growth model was developed based on the analysis of experiment data. According to the comparison of calculated values with experiment values, the calculated results are in good agreement with the experimental results.
