Description
Summary:The atomic level study of NiTi alloy at high temperature is very important to understand the mechanism of NiTi fabrication, in partial the process during the hot working. In the atomic investigation using molecular dynamics simulation, the use of the interatomic potential greatly affects the results. Therefore, the suitability of the interatomic potential applied in some specific condition has to be examined. In our previous work, we have tested the performance of EAM and MEAM potential to reproduce the lattice constant of NiTi alloy. Our previous results have shown that the MEAM potential work better than the EAM potential. In this research, we further investigate the performance of EAM and MEAM type potential to describe the melting behavior of nickel, titanium, and NiTi alloy. We find from the current result that the accuracy of the MEAM potential is better than EAM potential in high temperature MD simulations.
