Title

THERMAL EXPANSION BEHAVIOR OF AL/SIC COMPOSITES FABRICATED BY POWDER METALLURGY

Pages

  173-185

Abstract

 In this research, thermal expansion behavior of aluminum-matrix composites reinforced by SiC particles up to 500°C was investigated. For this purpose, thermal analysis equipments were utilized. The main objective is to explain thermal expansion behavior of aluminum-matrix composites reinforced by different percentages of SiC alongside the effect of reinforcement particles on thermal behavior of these materials that are used as base materials in electronic industries. Composites with different percentages of reinforcement (containing 10, 15, 20, and 25%) and different meshes (45, 100, and 150 m) of SiC reinforcement particles and Al-4%Cu alloy matrix were prepared by POWDER METALLURGY. Instant coefficient of thermal expansion which is a function of temperature was compared based on Turner's model and Shapry model with predictions from thennoelastic models. Thermal expansion behavior depends on various parameters such as microstructure, matrix deformation, and internal stresses. Dependence of copper-in- aluminum solution on temperature has a significant effect on THERMAL EXPANSION COEFFICIENT of Al-4%Cu alloy matrix and hence thennal behavior of the composite. Results of the experiments performed on the composites reveal that with increase of percentage of silisium carbide ceramic particles, the amount of THERMAL EXPANSION COEFFICIENT decreases.
