Investigation of effect of mechanical properties and Influence of Heat treatment on AISI 4140 steel

Abstract

The optimization methods in metal heating processes, considered to be a vital tool for continual improvement of output quality in products. In order to optimize the gains from the raw material of AISI 4140 alloy steel, an accurate process must be constructed. The carbon content in AISI4140 steel ranges from 0.38 to 0.43%. In this approach the mechanical properties mainly like Hardness, Yield Strength, Wear Resistance are amenable to modification via heat treatment. In the present work the objective is to test the chosen steel with various heat treatment processes and also analyze their microstructure. A comparative study made across the properties vs. heat treat processes. Finally, to choose the best heat treatment process and optimal properties that can be achieved.
