An accurate and simple model of stacking fault energy for alloys (soli
d solutions) has been developed based on the embedded-atom method. The
calculated value of stacking fault energy, 35 mJ/m(2) for 304 austeni
tic stainless steel, is in a good agreement with the experimental one,
30 mJ/m(2). In the present model we find that the Hirth's empirical r
elationship is also suitable for alloy.
