Sometimes materials developed for use in technology have some shortcomings in that some of their properties need to be treated or further improved. There are several techniques to treat the shortcomings of materials, such as mechanical treatment, electrical treatment, surface treatment, chemical treatment, and heat treatment, each of these techniques has its characteristics, and each in some way attempts to fix the deficiencies of technological materials. This review focused on the heat treatment technique. There are four main types of heat treatment techniques: annealing, normalizing, hardening, and tempering. Each of them heats the materials and samples differently and cools them in a different way. Annealing, normalizing, hardening, and tempering have significant effects on improving the mechanical properties of materials including hardness, tensile strength, elongation, grain size, roughness and so on. This review attempts to analyze each of the four different heat treatment techniques, and the effect of each on the physical properties of solids is studied by reviewing the literature works.
