摘要
采用压力熔渗法制备Al/金刚石复合材料,探讨金刚石粒度对复合材料微观形貌、力学性能和断口形貌的影响。结果表明复合材料的力学性能随金刚石粒径的减小逐渐升高,金刚石粒度为400/500目时,Al/金刚石复合材料的抗拉强度为145MPa,抗压强度为1020MPa,抗弯强度达到310MPa。
Diamond particles reinforced aluminum matrix composites were fabricated by squeeze casting method.The effect of diamond size on the microstructure,mechanical property and fracture morphology of composite were investigated.The results show that the mechanical properties of Al/diamond composite gradually increased with the decrease of particle size.Under diamond particle size of 400/500 mesh,the tensile strength of Al/diamond composite was 145MPa,compressive strength of 1020MPa,along with bending strength of 310MPa.
