| titleOfInvention | STEEL ALLOYS OF FOUR HIGH RESISTANCE PHASES. |
| abstract | A process for manufacturing high strength, ductile and corrosion resistant carbon steel, said process comprising: (a) heating an alloy composition at a temperature sufficiently high to form an initial microstructure comprising an austenite phase substantially free of martensite, said alloy composition having a martensite starting temperature of at least about 330 ° C, and comprising 0.03% to 0.35% carbon, 1.0% to 11.0% chromium, at least the 2.5% manganese, optionally up to 2% in total of one or more nickel, cobalt, aluminum, nitrogen, molybdenum, niobium, titanium and vanadium, optionally 0.1% to 3% silicon and the rest iron , along with inevitable impurities; (b) cooling said initial microstructure under conditions that cause the conversion thereof into an intermediate microstructure of austenite, ferrite and carbides, said intermediate microstructure comprising adjacent phases of austenite and ferrite with carbide precipitates dispersed in said ferrite phases, and substantially no carbide precipitates at the phase limits; and (c) cooling said intermediate microstructure under conditions that cause it to be converted to a final microstructure of martensite, austenite, ferrite and carbides, said final structure comprising regions of martensite-austenite consisting of martensite networks alternated with thin films of austenite, ferrite regions contiguous with said martensite-austenite regions and carbide precipitates dispersed in said ferrite regions, without carbide precipitates at the interfaces between said martensite networks and said austenite thin films, or at the interfaces between said regions of ferrite and said regions of martensite-austenite. |
