HEAT TREATMENT OF MEDIUM CARBON STEELS AND ANALYSE ITS PROPERTIES USING MODIFIED U.T.M

This project report aims to study and calculate two of the most fundamental properties of a metal – it’s Young’s Modulus of Elasticity and hardness. For this experiment, the metal chosen was Steel on which different heat treatment and hardening processes were conducted. Hardness test helps in measuring the resistance of a material to plastic deformation on indentation. Hardness is a feature of a given object, and not a basic physical property. The hardness values can be calculated on three different scales which helps in giving a better idea and precision about the material’s hardness. Young’s modulus of a material is an important attribute to understand for analyzing how the material will behave when the force is applied. In this experiment, Young’s Modulus was found by the application of Euler’s Buckling Formula. Buckling is the loss of stability that occurs when the applied compressive loads exceed a certain value causing the shape of the bar to change. The variables are calculated using the Universal Testing Machine (UTM), which is then substituted to find Young’s Modulus for different cases. The experimental values shows that Young’s modulus of heat-treated steels don’t vary much
