Abstract
The purpose of this research is to analyze different investigations that deal with heat treatments in Materials Science and Engineering, and shows the impact that they generate in the improvement of properties of various materials used in different industries, depending on their application or need. Through the state of the art it was possible to establish the importance and applications of heat treatments, which are important processes that allow controlling the structure of materials and improving their physical and mechanical properties, these treatments play a crucial role in the development and improvement of materials used in various industries. As a result of the research, the theoretical bases of heat treatments are clearly determined, explaining the different types of heat treatments and the diffusion and phase transformation phenomena of each process. Finally, it was possible to establish the true purposes of heat treatments, highlighting the importance in the optimization of mechanical properties such as strength, hardness, toughness and ductility, in addition, case studies are used to exemplify how the properties of metals have improved and finally mention advanced techniques such as hardening and refinement to obtain structures such as plastic, elastic, tensile and compressive properties.
