摘要

Aluminum matrix composites reinforced with micro-and nano-sized Al2O3 particles provide desirable characteristics for high-performance applications in aerospace, automobile, and military industries, because of their improved physical and mechanical properties. Selection of the best combination of ultimate strength and formability properties of the composites is a multiple attribute decision making problem where some criteria must be considered. In this study, A356/Al2O3 composites were prepared with different conditions such as the fabrication method, size, and weight fraction of reinforcement. These alternatives were ranked by analytic hierarchy process method. Analytic hierarchy process results revealed that the composite with 2 wt% nano-Al2O3 fabricated by compo-casting method was the preferred composite material
