Effect of Precipitation Hardening on Hardness and Microstructure of Austenitic Manganese Steel
Show more
Abstract: The effect of precipitation hardening on microstructure and hardness of Austenitic Manganese Steel has been studied. Samples of the steel were machined, autenitized at 1000℃ and held for one hour, water quenched and then aged at different temperatures and holding times. The samples were artificially aged at 600℃ and 700℃ and were held for one, two and three hours. Microstructures and hardness values of the samples were taken. It was found out that sample aged at 700℃ for 2 hours has its carbide particles finely dispersed on the austenite matrix. This led to an increase in the hardness.
