Thermodynamic Development of Austenite-Martensite Class Corrosion-Resistant Steels Intended for a Bimetal Cladding Layer

Resumo

Thermodynamic modeling is performed for regions of phase existence in economically alloyed corrosionresistant steels with the aim of determining the possibility of their use as a bimetal wear-resistant cladding layer. Quantitative evaluation is obtained for the form of nitrogen and oxygen present. It is demonstrated that for steels of the type in question introduction of niobium is only effective at the microalloying level.
