Low-carbon steels of superior mechanical and corrosion properties |
| abstract |
Alloy steel, which combines high corrosion resistance with high strength and high toughness, is achieved by dislocation type microstructures, in which dislocation martensite classes that do not substantially have twins repeat alternately with residual austenite thin films. Both dislocation martensite and residual austenite thin films are free of spontaneously tapered carbides, nitrides and carbon nitrides. This microstructure selects an alloy composition with a martensitic onset temperature (M s ) of 350 ° C. or higher and selects a cooling scheme that passes through the martensite transition range avoiding the area of spontaneous tempering from the austenite phase. Is obtained. |
