“…Main texture components are quite the same for the sample without deformation with the difference that the orientation {110}<111> moves toward {112}<111>, copper component. These results are in accordance with others works published in the literature [7][8][9] . The evolution of austenite texture with deformation for an AISI 304L stainless steel was studied by Ravi Kumar et al 8 and one of their conclusions is that the copper component will not increase density with high levels of deformation.…”

Deformation induced martensite in an AISI 301LN stainless steel: characterization and influence on pitting corrosion resistance

In austenitic stainless steels, plastic deformation can induce martensite formation. The induced martensite is related to the austenite (γ) instability at temperatures close or below room temperature. The metastability of austenite stainless steels increases with the decreasing of stacking fault energy (SFE). In this work, the deformation induced martensite was analyzed by X ray diffraction, electron back scatter diffraction (EBSD), magnetic methods and atomic force microscope (AFM) in samples of a low SFE austenitic stainless steel, AISI 301LN and compared with a medium SFE stainless steel, AISI 316L. Both techniques, X ray diffraction and EBSD, presented similar quantities for the α'-martensite. Texture results indicate that the crystallographic orientation of the formed α'-martensite is {001}<110> and {103}<110>. The morphology of α'-martensite was analyzed by AFM. Corrosion tests showed that deformation reduces pitting corrosion and generalized corrosion resistance in both steels.

The tensile behavior of hydrogen‐charged 304‐type austenitic stainless steel, with and without prestrain, is investigated. The specimens are thermally charged with hydrogen in 15 MPa hydrogen gas at 300 °C for 72 h. Tensile behavior of the specimen is compared with the specimen aged in vacuum at 300 °C. The effect of the charging condition on the stability of microstructure is determined by characterizing prestrained specimens before and after charging. The hydrogen content in the specimens is determined using thermal desorption spectroscopy (TDS). Analysis of X‐ray diffraction (XRD) data and electron backscattered diffraction (EBSD) shows that the fraction of martensite increases after charging in hydrogen by 5–10%. The fracture surfaces of the uncharged and charged specimens are examined for characteristic features. Flow stress and ductility of the charged and prestrained and charged specimens are discussed in terms of the martensite fraction and hydrogen content.
