Trends in the elastic response of binary early transition metal nitrides

Abstract

Motivated by an increasing demand for coherent data that can be used for\nselecting materials with properties tailored for specific application\nrequirements, we studied elastic response of nine binary early transition metal\nnitrides (ScN, TiN, VN, YN, ZrN, NbN, LaN, HfN, and TaN) and AlN. In\nparticular, single crystal elastic constants, Young's modulus in different\ncrystallographic directions, polycrystalline values of shear and Young's\nmoduli, and the elastic anisotropy factor were calculated. Additionally, we\nprovide estimates of the third order elastic constants for the ten binary\nnitrides.\n
