Effect of solution treatment on the texture and tensile properties of Mg₂B₂O_5W/2024Al composite

A 2024 aluminum matrix composite reinforced by Mg₂B₂O₅whiskers was fabricated by squeeze casting method. The effects of solution time on the texture and tensile properties are investigated. The results show that solution time has significant effect on the texture type and tensile properties of the composite. Fiber texture of 2024Al matrix was found in the as-cast composite and its evolution during solution process was analyzed. The results indicate that recrystallization process of 2024Al matrix is the main reason for the evolution of texture and the change of mechanical properties after solution treatment.
