Role of twin fraction on the hardening stage in cryodeformed FCC materials

Cryodeformation is a potential route to develop high-performance structural materials. The microstructure of cryodeformed material is very complex and varies with stacking fault energies (SFE). The present work focuses on developing a constitutive model for establishing the influence of twin fraction and cryodeformed microstructure on the work hardening behavior of cryodeformed materials with medium and low SFE. Transmission electron microscopy (TEM), X-ray diffraction, and tensile testing were used to support the experimental observations and mathematical model.
