Effect of Heat Treatment Processes on Metals and Alloys-A Review

Abstract

Heat treatment can be simply defined as heating, holding, and cooling of materials. The current review paper presents the various types of heat treatment processes done on the different metals and alloys. A comparative analysis of the effect of heat treatment on hard-ness, yield strength, and microstructure, etc. of the various metals and alloys has been presented in this paper. The literature has shown that the heat treatment resulted in the development of new phases along with the improvement of microstructural and mechanical properties of various metals and alloys. The paper also represents the consequence of microwave heat treatment done on various substrates. The final part of the paper discusses the suggested future work that can be done.
