Effect of Particles Alignment Anisotropy on the Fatigue Behaviors of Extruded Al2O3/2124 Aluminum Alloy Composites

Article Preview

Abstract:

Alignment of reinforcement particles was observed to affect the fatigue behaviors of extruded composites strongly. Micro-structure characterization showed a preferred orientation of the reinforcement particles parallel to the extrusion axis. As the reinforcement volume fraction increase, to some calculated values, the fatigue life and strength of the composite materials increases although the degree of particles alignment decreased.
