Abstract

In this paper, the phase-field oxidation mechanism of ultra-high temperature ZrB ₂/SiC ceramics is investigated theoretically. Firstly, a phase-field model is developed to analyze the oxidation behaviors of multiphase materials. Secondly, the evolutions of the porosity and the oxidation stress for the oxidized ZrB ₂/SiC ceramics with different temperatures and different oxygen partial pressures are predicted, and the influences of the mechanical factors on the oxidation behaviors of ZrB ₂/SiC ceramics are discussed. Finally, two-dimensional oxidation behaviors of ZrB ₂/SiC ceramics are simulated and analyzed.
