The process involves reheating hardened metal to a specific temperature below its critical point, then allowing it to cool. This heat treatment reduces brittleness, increases toughness, and relieves internal stresses induced during hardening. It is a crucial step in achieving the desired balance of hardness and ductility in metal components.
This process significantly enhances the material’s ability to withstand impact and deformation without fracturing. Historically, blacksmiths and metalworkers have utilized controlled heating and cooling techniques to optimize tools and weapons, understanding that properly treated metal exhibits superior performance and longevity. The procedure is essential for parts requiring both strength and resistance to shock.
