Summary

Residual strains and stresses were determined in three α-Al2O3/β-SiC whisker composite samples using X-ray diffraction. The samples were HP-29, a hot pressed sample containing 29 vol% SiC; S-10, a uniaxially cold pressed and sintered sample containing 10 vol% SiC and 2–3 vol% total porosity; and HP-10, a hot pressed sample containing 10 vol% SiC. The results of X-ray measurements made on three orthogonal faces on samples HP-29 and S-10 and on one face on sample HP-10 are presented. The effects of hot pressing vs cold pressing and sintering on the total residual strains and stresses in each phase are discussed.
