The design of an Fe-12Mn-O.2Ti alloy steel for low temperature use [PDF]
An investigation was made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-O 2Ti alloy steels. A two-phase(alpha + gamma) tempering in combination with cold working or hot working was identified as an effective treatment.
