摘要	The melting curve of NiTi alloy was predicted by using molecular dynamics simulations combining with the embedded atom model potential. The calculated thermal equation of state consists well with our previous results obtained from quasiharmonic Debye approximation. Fitting the well-known Simon form to our T(m) data yields the melting curves for NiTi: 1850(1+P/21.938)(0.328) (for one-phase method) and 1575(1+P/7.476)(0.305) (for two-phase method). The two-phase simulations can effectively eliminate the superheating in one-phase simulations. At 1 bar, the melting temperature of NiTi is 1575 +/- 25 K and the corresponding melting slope is 64 K/GPa. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3548936]
