Abstract

The present invention relates to a manganese steel alloy having a heat-treated micro structure comprising an alloy composition, an austenitic ferrous matrix, and formed refractory particles dispersed throughout the austenitic ferrous matrix such that at least 10% of the formed refractory particles are located within crystallites of the austenitic ferrous matrix, as opposed to being located at grain boundaries between the crystallites, and a method of producing the manganese steel alloy.
