the influence of temperature on stacking fault energy in Fe-based alloys

摘要

temperature has great influence of the stacking fault energy (SFE). Both SFE and dr_o/ D T for Fe-based alloys containing substitutional or interstitial atoms increase with increasing tempera- Ture. Based on the thermodynamic model of SFE, the equation formula (ill.) and those Expressions for three items involved are established.
