Abstract

Reversion studies have been carried out on Al-4, 8 and 12 at% Zn alloys through electrical resistivity measurements. The critical reversion temperatures were determined as 103, 162 and 183° C, respectively. Using these values along with earlier results, the solvus for Guinier-Preston (G-P) zones has been arrived at. The results hitherto obtained on the metastable equilibrium between G-P zones and the matrix in Al-Zn alloys have been discussed in the light of the new solvus.
