Hot working refers to processes where metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the material to recrystallize during deformation. This is important because recrystallization keeps the materials from strain hardening, which ultimately keeps the yield strength and hardness low and ductility high. This contrasts with cold working.

Famous quotes containing the words hot and/or working:
“Did you know, Putnam, that more murders are committed at 92 Fahrenheit than any other temperature? I read an article once. Lower temperatures, people are easygoing. Over 92, it’s too hot to move. But just 92, people get irritable.”
—Harry Essex (b. 1910)
“Our policy is directed not against any country or doctrine, but against hunger, poverty, desperation and chaos. Its purpose should be the revival of a working economy in the world so as to permit the emergence of political and social conditions in which free institutions can exist.”
—George Marshall (1880–1959)
