  • Ball milling of stainless steel scrap chips to produce

    Ball milling behaviour of austenitic stainless steel chips was studied. The results showed that ball milling led to the formation of nanoscale size martensite phase. The powder particles after ball milling had a dual structure consisting of austenite and martensite phases with a microhardness value twice greater than that of the original chips.
