Alloy Model for the Stacking Fault Energy

摘要

An accurate and simple model of stacking fault energy for alloys (solid solutions) has beendeveloped based on the embedded-atom method. The calculated value of stacking fault energy35 mJ/m2 for 304 austenitic stainless steel, is in a good agreement with the experimental one,30 mJ/m2. In the present model we find that the Hirth’s empirical relationship is also suitablefor alloy.
