    Experimental and numerical investigation of key microstructural features influencing the localization of plastic deformation in Fe-TiB2 metal matrix composite

    A new generation of iron-based matrix composite reinforced by TiB2 particles was deformed in tension to investigate at a mesoscopic scale the localization of plastic deformation in relation with characteristic mi...

    Particle interspacing effects on the mechanical behavior of a Fe–TiB2 metal matrix composite using FFT-based mesoscopic field dislocation mechanics

    This paper presents an application to metal matrix composites (MMCs) of an enhanced elasto-viscoplastic Fast Fourier Transform (EVP-FFT) formulation coupled with a phenomenological continuum Mesoscale Field Di...

    Electron backscattered diffraction study of ε/α′ martensitic variants induced by plastic deformation in 304 stainless steel

    The electron backscattered diffraction (EBSD) technique has been used to assess crystallographic features of the residual γ phase and the strain-induced ε/α′ martensites in a 304 stainless steel, tensile tested t...

    Specific analysis of EBSD data to study the texture inheritance due to the β → α phase transformation

    A specific processing of EBSD data is proposed to study the β → α texture inheritance of α titanium or α zirconium alloys. A non standard misorientation map is calculated to localise the colonies inherited fro...

    Study of the β-α phase transformations of a Ti-64 sheet induced from a high-temperature β state and a high-temperature α + β state

    The room-temperature α textures of Ti-64 sheets, inherited from the β-α phase transformation of high-temperature β textures of the material in the β and α + β fields, respectively, have been studied. The correspo...
