Numerical simulation of fracture of nanocrystals of the TiAl$_3$ intermetallic compound by the molecular dynamics method

Results of numerical simulations of fracture of nanocrystals of the TiAl$_3$ intermetallic compound by the molecular dynamics method are reported. The TiAl$_3$ nanocrystals are subjected to uniaxial tension in a wide range of temperatures (300–1200 K). It is demonstrated that tension of nanocrystals of the TiAl$_3$ intermetallic compound heated approximately up to 1000 K first leads to a phase transition from the crystalline to liquid state, followed by their fracture. Fracture of a heated TiAl$_3$ nanowire is preceded by deformation in the superplasticity regime.
