研究了粉末冶金制备的SiCw/2124Al复合材料的组织结构及物理、力学性能.结果表明,此复合材料的基体保持了原2124Al合金微晶粉末的组织特点;其SiC晶须在基体中分布均匀,界面结合良好,能使抗拉强度提高40%、弹性模量提高76%、热膨胀系数降低至基体的65%. The microstructures, mechanical properties and mechanical properties of SiCw / 2124Al composites prepared by powder metallurgy were studied.The results show that the matrix of the composites maintains the microstructure characteristics of the original 2124Al alloy powders and the SiC whiskers are uniformly distributed in the matrix, Good interfacial bonding results in a 40% increase in tensile strength, an increase in modulus of elasticity of 76%, and a reduction in thermal expansion to 65% of the matrix.
