The Analysis of Thermal Residual Stress for Metal Matrix Composite with Al/SiC Particles

Abstract

When a metal matrix composite is cooled down to room temperature from the fabrication or annealing temperature, residual stresses are induced in the composite due to the mismatch of the thermal expansion coefficients between the matrix and fiber. A method can be derived for calculating the particles due to differences in thermal expansion coefficients. Special attention is paid to creep deformation in the matrix phase. The analysis shows that considerable internal stresses and creep deformation appear in the composites when subjected to cooling. Keywords: Therma residual stress, Creeping behavior, Theses, Volume fraction.
