'Stainless steel' is a registered trade name for fcc, iron-chromium-nickel alloys. Stainless steels are most noted for their high corrosion resistance and reduced oxidation at elevated temperatures. Recently, a new series of iron-chromium-manganese alloys have been developed that have similar oxidation and corrosion resistance, but have significantly enhanced mechanical properties: greater strength, toughness, wear resistance, fatigue strength, higher creep strength, etc.. Much of the improved properties can be attributed to their high, interstitial solubility. This seminar will talk about the advantages and limitations of these manganese alloys, the material science behind the development of these steels, why they have enhanced properties, and some of their current applications.
