pressure range from 0 to 50 GPa and temperature range from 0 to 1600 K. Key words: Re2N; transition metal nitrides; elastic properties; thermodynamic properties 1 Introduction Transition metal nitrides... and refractory nature of many early transition metal nitrides, such as TiN, CrN and HfN. In contrast, not too much success has been achieved in exploring the late transition metal nitrides, especially......
. After about 5 min, the original phase disappears. No change in the crystal symmetry (space group I4/mmm) is observed above 1040 K.
