In this study, various techniques used in the modification of the grain structure of steel were considered. It was found that different heat treatment techniques cause changes in the grain structure of steel and subsequent improvement in the mechanical properties of the material. More so, the bimodal grain size, as well as the lamellar structure in steel, will lead to work hardening effect and improved ductility of the steel. The carburization technique also improves the mechanical properties such as hardenability, compressibility, tensile strength, and toughness. While nitriding effects will lead to excellent tribocorrosion performance. More importantly, these heat treatment techniques help to improve the resistance against cyclic load in different application environments. Thus, failures resulting from crack propagation and other failure modes are prevented. In this regard, structural failures are prevented by grain structure modification using heat techniques.
