Focused review on factors affecting martensitic stainless steels and super martensitic stainless steel passive film in the oil and gas field [PDF]

Martensitic and super martensitic stainless steels are widely used in the oil and gas industry for general corrosion mitigation in the presence of sweet corrosion (CO2) and sour corrosion (H2S), providing a cost-effective alternative to more expensive ...

Modelling of the austenite-martensite transformation in stainless and TRIP steels

AIP Conference Proceedings, 2013
The transformation of austenite to martensite is a dominant factor in the description of the constitutive behavior during forming of TRIP assisted steels. To predict this transformation different models are currently available. In this paper the transformation is regarded as a stress induced process based on the thermodynamic action of the local ...

Influence of microscopic strain heterogeneity on the formability of martensitic stainless steel

AIP Conference Proceedings, 2017
Both finite element modeling and mean field (Mori-Tanaka) modeling are used to predict the strain partitioning in the martensite-ferrite microstructure of an AISI 410 martensitic stainless steel. Numerical predictions reproduce experimental trends according to which macroscopic strength is increased when the dissolution of carbides leads to carbon ...
