Abstract

The heat treatment of steel changes its microstructure, its hardness and its tensile strength. These issues are of utmost importance as they are closely related to its uses and applications. This article is an experiment, conducted at the university laboratory of physical metallurgy. It assesses the abovementioned issues in the cases of various steel samples, each of which undergoes a different type of heat treatment. Using the appropriate methodology and techniques, various conclusions are drawn. The main objective of this article is to explain this methodology.
