精铸CAC702铸件组织和性能的研究

Study on Microstructure and Property of CAC702 Casting

CAC702是以铜铝系为基的铸造铝青铜合金,通过调整Al的含量、控制Fe和Ni的加入比例、改善冷却条件,来改变其组织结构,以提高材料的强韧性。

CA702 is casting aluminum bronze alloy based on copper aluminum. The microstructure of CAC702 was changed by adjusting the AI content, controlling the adding proportion of Fe and Ni, and improveing the cooling condition, with enhance the material obdumbility.
