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.
