Abstract:
study the effect of different levels of aluminum (1.5%, 2.0%, 2.5%, 3.0%, 3.5%), nickel (0.6%, 0.8%, 1.0%), cobalt (0.2%, 0.4%, 0.6%), yttrium (0.01%, 0.03%, 0.05%) on the characteristics and structure of Cu-22.7Zn brass as-cast. The results show that all above elements added can refine brass grains on extent, change the size of phase, and improve the brass hardness, tensile strength and corrosion resistance. When the content is 3.5% in the alloy, the hardness of brass increases to 78.7HRB, up 6% compare with Cu-22.7Zn brass. With 1.0% Ni, the strength of the alloy raises to 76.5 HRB, increased by 3.6%. Cu-22.7Zn-3.4Al as-cast alloy, its strength of alloy increases 12.5% with 0.6% Co, and enhances 9.8% with 0.03% Y.
