Effect of Precipitation Hardening on Hardness and Microstructure of Austenitic Manganese Steel ()
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.
