| Abstract: | CuO/Al reaction in situ composites were manufactured with stirring casting process, their mechanical properties were studied, and then their microstructure, phase constituent, and fracture appearance were analyzed by XRD and SEM. Strength and hardness of the composites gained a great improvement compared with matrix alloy. The tensile strength of composites containing 10%CuO rose by 52.3% and hardness was nearly doubled. Fracturing appearance featured toughness characteristics and the fracture originated mainly from the casting defect slag holes. |
