Abstract The yield strength of moissanite was investigated at pressures up to 18.3 GPa and temperatures up to 1200 °C by analyzing the peak shapes of diffraction lines from a powder sample. At room temperature, the moissanite crystal behaves elastically with increasing pressure up to 13.7 GPa. At higher pressures applied, the sample is yielded; the yield strength of moissanite is determined to be 13.6 GPa. Upon heating at 18.3 GPa, significant stress relaxation is observed at temperatures above…

TLDR
First-principles calculations mostly agree with the experimental results, such as mechanical and dynamic stability and elastic anisotropy, but predicted axial modulus Kb by modeling is significantly smaller than the experimentally determined value, resulting in a sizable discrepancy between experimental (170.0 GPa) and theoretical (121.3 GPa).
