Abstract

Fabrication of dense Cu/40CF metal matrix composites for heat sink applications by hydrothermal sintering at low temperature (P = 250 MPa; T = 265 °C, t_sinter = 60 min; water quantity = 5 wt%) is reported. Study of various sintering parameters and their influence on densification are investigated. Comparative thermal and microstructural properties of hydrothermally sintered samples with the conventionally used uniaxial hot-pressing samples on Cu/40CF material show considerable improvements, namely increase of thermal conductivity (TC) and decrease of coefficient of thermal expansion (CTE). Hydrothermal sintering yields, through a dissolution/precipitation mechanism, quasi-isotropic thermal properties (TC = 300 W/mK and CTE = 8 10⁻⁶/K).
