High Thermal Conductivity and Low Thermal Expansion of Al-Si Alloys
An aluminum-silicon alloy–graphite composite material is produced using existing hot-pressing technology and equipment. Aluminum-silicon alloy powder and flake graphite sheets are thoroughly mixed and added to a graphite mold. Under an argon protective atmosphere, the combined effects of high pressure and high temperature increase the composite material's density while suppressing the interfacial reaction between aluminum and carbon. This approach resolves the issue of interfacial defects that affect the strength and thermal conductivity of the composite. During the preparation process of the aluminum-silicon–graphite composite, the thermal conductivity of the material can be controlled and optimized by adjusting process parameters such as the hot-pressing pressure, duration, and temperature of the vacuum hot-pressing equipment.
