摘要：
The stacking fault energy of six iron-base shape memory alloys can be calculated by the extended dislocation node method. The results show that Ni and Mn increase the stacking fault energy of the alloys, while Cr and Si decrease the stacking fault energy. An expression relating the alloy elements Ni, Cr, Mn, and Si to the stacking fault energy of the iron-base shape memory alloys is provided. The effective ratio of the alloying elements on the Stacking fault energy of iron-base alloys is given: %Cr: %Ni: %Mn: %Si = -1.1: 1.64: 0.21: -4.45. (C) 1999 Elsevier Science B.V.
