| Abstract: | The calculation model of stacking fault energy in iron-base alloy, the sources of all thermodynamic parameters and actual examples related to calculation of the energy are introduced. And also the principle and method for determining the stacking fault probability in steel by X-ray diffraction are discussed, and thus gives the following three relational expressions between the stacking fault probability and compositions in Fe-Mn-Si-C alloy, the stacking fault energy and stacking fault probability and the stacking fault probability and the driving force of martensite transformation, which can provide the fundamental basis for develoDinz TWIP steels. |
