Effect of Cu or Ag Addition on Tensile Deformation in Al‐Zn‐Mg Alloys

In this work, Al-Zn-Mg alloys, which were added with Cu or Ag, were prepared to compare the effect of the additional elements on tensile deformation. Hardness measurement, tensile test, SEM observation have been performed in order to understand the relationship between tensile deformation and crystallographic orientation of Al-Zn-Mg alloys. The addition of Cu or Ag increases the tensile strength of the alloy though decreases the elongation slightly comparing with the base alloy.
