Differentiate annealing and tempering heat treatment processes.
Heat treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. When performing the cooling step of the tempering process, knife makers have used material such as clay to cover portions of the blade to slow the cooling rate of the covered steel. Why may this technique be beneficial for making a sword which holds a sharp edge while remaining flexible enough to withstand the forces subjected to it in battle?
Enumerate and define the three types of heat treatment.
