Studies On Static and Fatigue Properties of Al2219 Reinforced with B4C

Abstract

The static and fatigue behavior of Al 2219/B4C particle metal matrix composites are examined in this work. Using a stir casting procedure, 200 micron B4C particles with different weight percentages of 4 and 6 reinforced to create the composites. To examine how reinforcing particles improved fatigue and static behavior. The generated composites' performance compared to that of the alloy Al 2219.The outcome shows that adding B4C increases the fatigue strength of composites over the alloy. Using an optical microscope, the uniform distribution of the reinforcement particles within the matrix investigated. Additionally, both attributes significantly improved when the weight percentage of B4C reinforcement in the matrix was increased. There were fewer cycles as the load increased, suggesting that the load had a greater impact on the fatigue strength. In general, flexural strength and fatigue strength.
