The role of microstructure in fatigue crack initiation of 9-12%Cr reduced activation ferritic-martensitic steel
(Elsevier, 2015-11)
Electron back-scattered diffraction together with scanning and transmission electron microscopy were used to study nucleation of microstructural fatigue cracks in reduced-activation ferritic-martensitic steel, EUROFER 97. ...
The role of microstructure in fatigue crack initiation and propagation in 9-12Cr ferritic-martensitic steels
(Elsevier, 2014-06)
The present paper presents low-cycle fatigue results about cyclic behaviour, the evolution of the dislocation structure and the nucleation and propagation of microstructural cracks in commercial ferritic-martensitic steel ...
Modeling the mechanical response of a dual-phase steel based on individual-phase tensile properties
(2020)
In this work, the engineering stress-strain tensile curve and the force-deflection bending curve of two Dual-Phase (DP) steels are modeled, combining the mechanical data of fully ferritic and fully martensitic steels. The ...
Cyclic Deformation and Microstructural Behavior of Reduced Activation Ferritic-Martensitic Steels
(Taylor & Francis, 2014-01)
The present paper presents results about cyclic behaviour and the evolution of the dislocation structure of reduced activation ferritic–martensitic steels and commercial martensitic steels AISI 410 and 420. The variation ...
Characterization of an ASTM A335 P91 ferritic-martensitic steel after continuous cooling cycles at moderate rates
(Elsevier, 2019-02)
In this contribution some aspects of the behavior of the ASTM A335 P91 (9Cr1MoVNbN) steel subjected to continuous cooling cycles under fixed austenitization conditions are studied. Representative samples of the structures ...
Effect of initial microstructure on surface relief and fatigue crack initiation in AISI 410 ferritic-martensitic steel
(Wiley Blackwell Publishing, Inc, 2019-01)
This work is focused on the effect of the initial tempered-lath microstructure on the surface relief and nucleation of microstructurally short fatigue cracks developed during low-cycle fatigue tests of the ferritic-martensitic ...
Reverse strain-induced martensitic transformation of the ferrite to austenite in duplex stainless steels
(2016)
© 2016, Springer Science+Business Media New York.The possibility of a reverse strain-induced martensitic transformation (RSIMT) of ferrite into austenite was evaluated in two duplex stainless steels (DSS) solution treated ...

Grãos ultrafinos por laminação a morno e recozimento intercrítico
(2006-11-01)
Grain refinement of low carbon steel via the warm deformation of martensite during torsion testing was investigated. At the beginning of straining, laths with high dislocation density were observed. After large deformations, ...
