The results show that the composite is dense and silicon particles are distributed uniformly. Transmission electron microscope observations show that stacking faults with high density, twins and dislocations are found in silicon particles. The Si-Al interfaces are well-bonded and no interface reactants are found. The dislocations and eutectic silicon precipitates are observed in LD11 matrix. Sip/LD11 composite has low density of 2.4 g/cm3, low coefficient of thermal expansion of 8.1×10-6/K, high thermal conductivity of 161.3 W/, and the annealing treatment can reduce the CTE and improve the thermal conductivity.

研究结果表明：复合材料组织致密，颗粒分布均匀；透射电镜观察发现，在Si颗粒内部存在高密度的层错，同时还存在孪晶和位错； Si-Al界面结合状况良好，无界面反应物； LD11铝合金中存在位错和析出的共晶Si；复合材料具有低密度(2.4 g/cm3)，低热膨胀系数(8.1×10-6/K)，高热导率161.3 W/(m·K的特性，可以通过退火处理进一步降低其热膨胀系数，提高热导率。
