The following data were obtained when a cold-worked metal was annealed. (a) Estimate the recovery, recrystallization, and grain growth temperatures; (b) recommend a suitable temperature for a stress-relief heat treatment; (c) recommend a suitable temperature for a hot-working process; and (d) estimate the melting temperature of the alloy.
