Estimation of thermal expansion behaviour of some refractory carbides and nitrides
- 93 Downloads
Lattice parameters of some refractory carbides and nitrides were estimated up to 2400 K using an empirical approach. The computed lattice parameters are in very close agreement (±0.5%) with the values calculated from experimental thermal expansion data reported in the literature. This empirical approach with modifications may be applicable to the prediction of the thermal expansion behaviour of other classes of high temperature materials.
