Abstract

A new kind of copper matrix composites with different volume fractions of β-eucryptite (Euc) particles was successfully fabricated by hot-pressed sintering. The microstructure of Euc/Cu composites was studied by scanning electron microscope and transmission electron microscope. The thermal physical properties of Euc/Cu composites were analyzed by means of thermal dilatometer and thermal conductivity tester. Results show that the effects of volume fraction of β-eucryptite particles on the thermal expansion coefficient and thermal conductivity of the composites are significant. When the volume fraction of β-eucryptite particles is more than 40%, the compactness of Euc/Cu composites decreases obviously. The thermal expansion coefficient of the composites is in the range of (9-15.4)×10^-6/K, which is much lower than that of copper, and thermal conductivity of the composites is 50-170 W/m·K.
