The soft temperature of copper matrix could be effectively improved and thermal expansion of copper matrix could be effectively restrained by the AlN particles; Under the action of porosity and thermal stresses, the thermal expansion curve of AlNp/Cu composites became non-linear with the particle volume contents increasing to a certain extent.

结果表明：AlN的加入能够提高铜基体的软化温度且对铜基体的热膨胀起到明显的约束作用；在孔隙与热应力共同作用下，AlN颗粒含量达到一定程度时，AlNp／Cu复合材料膨胀曲线随温度的上升将产生非线性变化；加热过程中热应力造成的基体塑性变形使热循环后复合材料存在残余正应变。
