Journal ArticleDOI
Measurement of stored energy in Fe–48%Ni alloys strongly cold-rolled using three approaches: Neutron diffraction, Dillamore and KAM approaches
Yanick Ateba Betanda,Anne-Laure Helbert,François Brisset,Marie-Hélène Mathon,Thierry Waeckerle,Thierry Baudin +5 more
TL;DR: In this article, the authors measured the stored energy in two Fe-48%Ni cold-rolled samples using three different approaches: the neutron diffraction method based on peak broadening, the Kernel Average misorientation (KAM) and the Dillamore methods both based on the misoriented and dislocation cell size estimation using EBSD (Electron Back Scatter Diffraction) data.
Journal ArticleDOI
Influence of stored energy on twin formation during primary recrystallization
Wei Wang,François Brisset,Anne-Laure Helbert,Denis Solas,I. Drouelle,M.H. Mathon,Thierry Baudin +6 more
TL;DR: In this article, a nickel-based alloy with low stacking fault energy is cold rolled with different strain amounts followed by an annealing at high temperature, and the twin formation during primary recrystallization is also determined during this stage as a function of deformation.
Journal ArticleDOI
Microstructures and textures of a Cu–Ni–Si alloy processed by high-pressure torsion
Abdel Yazid Khereddine,Fayçal Hadj Larbi,Hiba Azzeddine,Thierry Baudin,François Brisset,Anne-Laure Helbert,Marie-Hélène Mathon,Megumi Kawasaki,Megumi Kawasaki,Djamel Bradai,Terence G. Langdon,Terence G. Langdon +11 more
TL;DR: In this paper, the evolution of microstructure and texture in a commercial Cu-2.5%Ni-0.6%Si alloy during processing by high-pressure torsion (HPT) at room temperature up to a maximum of 10 turns was evaluated.
Journal ArticleDOI
Investigation of microstructure and texture evolution of a Mg/Al laminated composite elaborated by accumulative roll bonding
Walid Habila,Hiba Azzeddine,Brahim Mehdi,Kamel Tirsatine,Thierry Baudin,Anne-Laure Helbert,François Brisset,Sébastien Gautrot,Marie-Hélène Mathon,Djamel Bradai +9 more
TL;DR: The microstructure and texture of an Al1050/AZ31/Al1050 laminated composite fabricated by accumulative roll bonding at 400°C up to 5 cycles are investigated using Electron BackScatter Diffraction, neutron diffraction, microhardness measurements and tensile tests.
Journal ArticleDOI
Formation of annealing twins during primary recrystallization of two low stacking fault energy Ni-based alloys
Wei Wang,Sylvie Lartigue-Korinek,François Brisset,Anne-Laure Helbert,Julie Bourgon,Thierry Baudin +5 more
TL;DR: In this paper, the first stages of recrystallization are analyzed in low stacking fault energy nickel alloys cold rolled and subsequently annealed at 700°C for 6min.
