Comparison: Cold Working and Hot Working of Metals Metallurgy

WebComparison # Cold Working: 1. Cold working is done at a temperature below the value required for recrystallization, so no appreciable recovery takes place during deformation. 2. Hardening is not eliminated as working is done at a temperature below recrystallization, so this is always accompanied by strain hardening. 3. WebThe technical definitions of both hot and cold work refer to the recrystallization temperature of the metal. Hot working occurs when metal is deformed above its recrystallization temperature. In contrast, cold … fredlow123 https://sproutedflax.com
