L’alliage CuCrZr est utilisé dans les machines de fusion notamment pour des composants refroidis face au plasma, à cause de ses bonnes propriétés thermiques et mécaniques. Cependant, le retour d’expérience sur plusieurs tokamaks, et plus particulièrement T ...
Solutionizing and quenching are the key steps in the fabrication of heat-treatable aluminum parts such as AA2618 compressor impellers for turbochargers as they highly impact the mechanical characteristics of the product. In particular, quenching induces re ...
Residual stress state in planar tubular K-joints, in the chord within the gap region between the two braces, is studied using numerical weld modelling. The motivation comes from past full-scale fatigue tests on tubular trusses made of various steel grades ...
Tubular bridge design has to deal with fatigue issues. The fatigue susceptibility of these bridges, composed of circular hollow section profiles welded together in K-joints, is mainly due to stress concentrations, to welding imperfections and to tensile re ...
The GP(I) zone formation during quench is simulated in an industrial Aluminumalloy AA7449 75mmthick plate by using a multi-class precipitation model. For this purpose, results of in situ SAXS experiments are reported. A methodology is presented that takes ...
