Comparative Study of the Application of Forge Micro-Alloy and As-Cast Microalloy Steel in Automotive Application

Abstract

Automotive industry play decisive role In the economic growth of the country. The major challenge in front of automotive industry is to produce light weight without reducing strength parts such as connecting rod and driveline component, this can be achieved by using high strength low alloy steel. In all metal forming process forged parts posses maximum yield strength because of the preferred orientation of grains. Therefore,present research work focused on Micro structural and Mechanical Behaviour of As- Cast and Hot Forged Micro alloy Steel. Effect of thermo-mechanical processing and cooling rate is also studied.Characterization study of As- cast steel and hot forged steel is studied using optical and SEM microscope. The tensile testing performed on Instron testing machine. It is found that due to the thermomechanical processing of steel there is formation of strain induced precipitate that benefit in terms of impact strength, toughness of steel.
