U-V 0,2 wt% alloy deformation contribution study. Hydroforming structural states definition
Description
The plastic deformation of the alpha phase U-V 0.2wt alloy is a twinning and slip process. Hot direct rolling in alpha phase greatly changes the mechanical properties of the alloy and gives an anisotropic texture in the sheet plane. After complete recristallisation heat treatment the α rolled alloy has mechanical properties highly isotropic in the sheet plane. The ability to forming is important at room temperature. This grain refined method using strain hardening-recristallisation, can be successfully applied to a 400.10-6 carbon alloy: the alpha structure is then refined up to 15μm grain size and tensile properties are improved (R>850MPa, A=25%)

En phase α, la deformation plastique de l'alliage U-0,2%V se fait par maclage ou par glissements. Le laminage unidirectionnel a chaud, en phase α, modifie fortement les caracteristiques mecaniques du materiau et introduit une anisotropie dans le plan des toles. Apres recuit de recristallisation totale, l'alliage fortement ecroui en phase α, possede des caracteristiques mecaniques interessantes, sensiblement isotropes dans le plan des toles et une bonne aptitude a la mise en forme a la temperature ambiante. Cette methode d'affinage par ecrouissage-recristallisation peut etre appliquee avec succes a l'alliage U-0,2%V contenant 400 x 10-6 de C. La structure α de ce materiau est alors considerablement affinee (diametre moyen des grains = 15 μm) et les proprietes mecaniques sont satisfaisantes (R > 850 MPa, A=25%)Files
