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 obtaining a high-strength, high-electrical- conductivity wire;
(c) Recommend a suitable temperature for a hot working process; and
(d) Estimate the melting temperature of the alloy.
