Effect of Elements on Characteristics and Structure of Cu-22.7Zn Brass As-cast
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.
