What Is Hot Working? Hot working process metals are plastically deformed above their re-crystallization temperature. Being above the re-crystallization temperature allows the material to re-crystallize during formation. This is important because re-crystallization keeps the materials from strain hardening which ultimately keeps the yield strength and hardness low and ductility high. The ultimate goal of metal … Read more
