摘要：

The fracture‐toughness‐determining mechanism of silicon carbide with additions of yttria and alumina was studied. Observations of indentation crack profiles revealed that significant crack deflection had occurred. Median deflection angles increased with increased volume fractions of the second phases, which was accompanied by increased fracture toughness. Copyright © 1990, Wiley Blackwell. All rights reserved
