- Abstract:
- The effect of zinc on the microstructures and mechanical properties of an Al-Cu-Mg-Ag alloy was investigated using optical microscope,differential thermal scanners,scanning electron microscope,hardness and tensile property test.The results showed that the addition of Zn did not change the morphology and composition of the second phase,the best homogenization treatment of the alloy was 500 ℃ × 24 h.The peak aging hardness was increased from 169 MHV to 182 MHV,the tensile strength and yield strength at room temperature were increased by 23 MPa and 27 MPa,respectively.And the elongation of the alloy was still kept at a high level of 14％.The reason could be the solution of the zinc increase the crystal lattice distortion,and then lead to the improvement of the mechanical properties.
