| Popis: | Recent advances in processing technologies have made alloying elevated concentrations of nitrogen to ferritic iron alloys possible resulting in materials with unique microstructures, with enhanced corrosion and wear resistance, and with increased toughness and tensile strength. In this study, high-pressure melting and casting was used to add nitrogen to a commercial iron-carbon alloy resulting an austenitic--ferritic/martensitic alloy without formation of carbide and/or nitride precipitates. Both carbon and nitrogen are known austenite stabilizers and the lack of cooperation and coordination between the interstitial carbon and nitrogen concentrations apparently alters the kinetics of the austenitic transformation and restricts the formation of precipitates. |
