| Abstract: | The chemical composition of Al-Zn bush alloy was selected,and the microstructures observation,EDS and mechanical properties test of the prepared Al-Zn alloy were carried out.It is shown that,when the alloy composition is within its designed mass fraction,the phases of Mg2Si,CuAl 2,S(Al2Mg Cu),Pb,Sn and Al6(MnSiFe) distributes in the matrix of Al-Zn-Cu.After the homogenization treatment of 500 ℃×6 h,rolling and 300 ℃×1 h annealing,the ultimate tensile strength is 180 to 205 MPa,the elongtation rate is 16% to 18% and the microhardness(HV) is 54.7. |
