Precipitation kinetics in Ag–2 wt% Cu and Ag–2 wt% Cu–0.5 wt% In alloys during transformation

The effect of quenching rate on the stress–strain characteristics of Ag–2 wt% Cu and Ag–2 wt% Cu–0.5 wt% In alloys was investigated in the temperature range from 723 K to 923 K. The work-hardening parameters σ y, σ f, and χ, were found to decrease with increasing aging temperature exhibiting maxima...

description The effect of quenching rate on the stress–strain characteristics of Ag–2 wt% Cu and Ag–2 wt% Cu–0.5 wt% In alloys was investigated in the temperature range from 723 K to 923 K. The work-hardening parameters σ y, σ f, and χ, were found to decrease with increasing aging temperature exhibiting maxima at 823 K. The activation energies of the fracture mechanisms before and after transformation were found to be 22.1 and 39.4 kJ/mol, respectively, characterizing a dislocations intersection and grain boundary diffusion mechanisms in Ag for quenched and slowly cooled samples. An increase in strength was observed for the alloy containing (In). This was attributed to the tendency of (In) atoms to segregate at grain boundaries, causing grain size refinement.
