摘要：

The many-body potentials of TiAl alloy were constructed by empirical fitting to the properties of the L1(0)TiAl tetragonal phase and the pressure-volume relationship. The properties and stable configurations for point defects and their aggregates, and the activation energies for vacancy migration are simulated in TiAl intermetallic compounds using molecular dynamics.
