Twin fault probability

WebMar 21, 2024 · The twin formation probability (P tw) is directly proportional to the stacking fault formation probability (P sf). Due to fact that the SFE value of the CrCoNi MEA is low, the stacking fault formation probability ( P sf ) and twin formation probability ( P tw ) of the CrCoNi MEA are at a high level. WebJun 17, 2024 · In this case, the twin-fault probability was not determined, since for hcp structures, there are four different types of twins, and for the determination of the twin-fault probability, the type of twins must be known . For the fcc phase, twin faults exist only on the {111} crystallographic planes.
