Effect of Thermomechanical Treatment on Mechanical Behaviour and Microstructure of Low Alloy Steel
The present study was undertaken to investigate the effect of thermo-mechanical treatment (TMT)on the microstructure and mechanical behaviour of low alloy steel.Hot forging is carried out at 1200℃ using mechanical press of 500 and 800 ton.The effect of hot forging reduction ratios (1.11 and 1.29) on the hardness and mechanical properties are studied.TMT samples are given different heat treatment i.e.annealing (A),normalizing (N),hardening (H),hardening and tempering (H/T)and their corresponding impact toughness are obtained.Selected heat treatment (normalizing and annealing) are given to tensile test samples and their corresponding strength and ductility are obtained.Ultimate tensile,0.2% offset yield strength and percent elongation are measured.Hardness and impact toughness measurements were carded out for all alloy conditions.
