Abstract
Thermal residual stresses of ZrB2-17 vol% SiC, ZrB2-32 vol% SiC, and ZrB2-45 vol% SiC ceramics were estimated using the piezospectroscopy. High spatial resolution (~0.7 μm) 2D Raman mapping was used to determine the average peak position of SiC in all three ZrB2-SiC composites in addition to the peak position in pure SiC. A novel filtering technique was used to refine the relevant FLO SiC peak of interest, which included a combination of filtering procedures based on peak intensity, Full Width at Half Maximum, and its position. After data filtering, the thermal residual stresses in ZrB2-SiC composites were estimated using FLO average peak positions using piezospectroscopic coefficients available in the literature. The obtained results were also compared with theoretical calculations models developed in the literature.
