摘要: A low-carbon, titanium and niobium (Ti-Nb) bearing a low-carbon titanium, copper (Ti-Nb-Cu) ultra high strength steel have been thermo-mechanically processed on laboratory scale unit. Evolution of microstructure mechanical properties the above air cooled steels studied at different finish rolling temperatures (FRTs). Microstructural characterization reveals largely mixture granular bainite bainitic ferrite along with precipitation microalloying carbide/carbonitride particles and/or Cu-rich precipitates. yields higher yield (1114-1143 MPa) tensile (1591-1688 moderate ductility (12-13%) as compared to having (934-996 combined (1434-1464 similar (13%) for selected range 850-750°C FRT. Due strength-ductility combinations, these present investigated can be regarded replacement material ballistic applications well other sectors like defense, pipeline, cars, pressure vessels, ships, offshore platforms, aircraft undercarriages rocket motor casings etc. Key words: Thermo-mechanical controlled processing, steel, microstructure, properties.
