| Popis: | Chromium corrosion-resistant steels alloyed with nitrogen are studied by experiment. It is shown that depending on chemical composition and process parameters the structure of the chromium steels obtained may be martensitic with a minimum residual austenite content, martensitic with a greater content of residual austenite, or three-phase, consisting of martensite, residual austenite, and ferrite. The possibility is demonstrated of increasing steel martensite ductility by forming a specific amount of austenite within the steel structure. |
