Abstract
Thermal residual stresses in Ti-6Al-4V alloy reinforced with silicon c arbide (SiC) and sapphire alumina (Al2O3) films are estimated based on an elastic-viscoplastic micromechanics analysis. Effects of fibre vol ume fraction and different manufacturing procedures are considered and comparisons made with published experimental results for the SiC fibr e composite. Stress components in the Ti-6-4/Al2O3 are generally less than half the corresponding values in the Ti-6-4/SiC composite.
