Conférence invitée(2011)The predictions of the constitutive model agree with experimental results in terms of macroscopy stress-strain curves and volume fraction of martensite formed during loading
-
Conférence invitée(2010)In this investigation, the thermo-viscoplastic behaviour of the steel AISI 304 has been examined. The experimental characterization of the material has been conducted in tension under wide ranges of strain rates.An analytical ...
-
Conférence invitée(2015)Finally, the same in situ biaxial tensile tests were also performed with both SEM and XRD, first at low temperature in order to study the influence of temperature on the material behaviour and especially on martensite ...
-
Conférence invitée(Trans Tech publications, 2015)After analazing,the microstructure of the thixoforged parts, some mechanisms of material flow are proposed.
-
Conférence invitée(2005)A specific in-situ tensile device has been set up in an X-Ray diffractometer. Stress can be measured at low temperature during loading in the baintic steel and in the ferritic phase. A two-scale modeling has been proposed ...

Experimental study of Built-Up Layer formation during machining of High Strength free cutting steel Article dans une revue avec comité de lecture(Elsevier, 2016)Machinability of high-strength steels can be improved without degrading the mechanical properties using metallurgical solutions to create or retain non-metallic inclusions. Such a metallurgical treatment usually leads, ...

Article dans une revue avec comité de lecture(Elsevier, 2016)Sheet piles are produced by hot rolling, a cooling step and, if required, by a straightening operation. Numerical simulations indicate that the stress field is almost homogeneous through the thickness, justifying the ...
