The variation of tensile characteristics of Al-2Â wt.%Ag and Al-2Â wt.%Ag-1Â wt.%Sn alloys during transformation

▶ Work hardening characteristics of Al alloys during phase transformation. ▶ The addition of Sn to Al-2 wt.% Ag alloy formation of vacancy-clusters formed in the ternary alloy which enhance the coarsening of GP zones. ▶ The hardening parameters of the quenched samples are higher than those of the slowly cooled samples. ▶ The activation energies of the fracture mechanism in both alloys was around 26.8 ± 3 kJ/mol and 34.6 ± 3 kJ/mol before and after transformation attributed to dislocation intersection mechanism and grain boundary diffusion mechanism.
