【Abstract】 Aiming to meet the challenge of the shape complexity and high plasticity demanded for the upper connective plate(UCP) in motorcycle, a high plasticity Al Si alloy named HGZL 02 was developed by optimizing the chemical composition and casting process. Premium UCP castings were obtained by using optimized casting process. Results show that fine and dense microstructure are obtained in the UCP castings. An average of 224 MPa in ultimate tensile strength, 149 MPa in yield strength and 13.2% in elongation are achieved for T6 heat treated UPS castings.更多还原
