TABLE 1.

The 2NN MEAM interaction potential parameters for Ti, Cr and N. The units of the cohesive energy E _cand the equilibrium nearest-neighbor distance r _e are eV and Å, respectively. All the other parameters are dimensionless. The reference structures for Ti, Cr and N are hcp, fcc and dimer, respectively.
