Abstract

In this work, we have used molecular dynamics (MD) to obtain an atomistic description of the melting, glass formation and crystallization process in CuTi alloy. We present the tight-binding (TB) many body potentials for the CuTi system which were constructed so as to reproduce a number of properties of the B11 CuTi compound (tetragonal structure). It has been shown that these potentials ensure the stability of the CuTi crystal structure against alternate structures and closely reproduce the melting temperature of CuTi. We have also considered several cooling rates to investigate its effect on the glass transition and crystallization temperatures. The pair distribution functions (PDF), Wendt–Abraham (WA) parameters and the changes of volume were calculated to determine glass transition temperature and crystal formation of CuTi alloy..
