Abstract
Results of numerical simulations of fracture of nanocrystals of the TiAl3 intermetallic compound by the molecular dynamics method are reported. The TiAl3 nanocrystals are subjected to uniaxial tension in a wide range of temperatures (300–1200 K). It is demonstrated that tension of nanocrystals of the TiAl3intermetallic compound heated approximately up to 1000 K first leads to a phase transition from the crystalline to liquid state, followed by fracture. Fracture of a heated TiAl3 nanowire is preceded by deformation in the superplasticity regime.
