Thermal residual stresses in SiC matrix – MoSi 2 reinforced composites were investigated by Raman microprobe spectroscopy and X‐ray diffraction. The introduction of 10 and 30 vol% MoSi 2 particles generated compressive stresses in the SiC matrix, with magnitude of about –80 and –190 MPa, respectively. A typical residual stress map obtained through Raman spectroscopy for the SiC‐30 vol% MoSi 2 composite is shown in the accompanying figure.
