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).

据报道在低温下通过水热烧结（P = 250 MPa; T = 265°C，t_烧结= 60 min;水量= 5 wt。％）制备用于散热器应用的致密Cu / 40CF金属基复合材料。研究了各种烧结参数及其对致密化的影响。在Cu / 40CF材料上，水热烧结样品与常规使用的单轴热压样品的比较热和微观结构性能显示出显着的改进，即导热系数（TC）的增加和热膨胀系数（CTE）的降低。水热烧结通过溶解/沉淀机理产生准各向同性的热特性（TC = 300 W / mK和CTE = 8 10 ^-6 / K）。
