Deformation-Induced Dissolution of Ni3Al Particles in Nickel: Atomistic Simulation

详细

Abstract—The simulation of the dissolution of the intermetallic Ni₃Al particles in the nickel matrix at low temperatures was performed using the molecular dynamics method. The simulated strain is comparable with that previously obtained for the case of dissolution of these particles in austenitic steels subjected to shear under pressure at low temperatures (up to 77 K). It is worth noting the importance of the twinning in the dissolution. The effects of conditions and kinetics of deformation, as well as possible origins, are discussed.
