The single-crystal elastic constants of cubic (3C) SiC to 1000° C

  • Z. Li

Experimental measurements of the polycrystalline elastic moduli of the cubic (3C) beta polytype of SiC at elevated temperatures and the room-temperature single-crystal elastic constants were combined through equations that relate the two to determine the stiffnesses Cij and the compliances Sij to 1000° C. The results demonstrate a general method for estimating the elevated temperature single-crystal constants of cubic crystals and illustrate that the cubic (3C) beta polytype of SiC becomes more elastically anisotropic at elevated temperatures.
