Abstract

Experimental evolution of Lankford anisotropy coefficient R(α) versus the amount of strain in tension E11 and versus the angle α between rolling direction and the tensile test direction for Titanium, Zirconium (Zr 702) and Zircaloy 4 (Zr 704) thin sheets points out that R(α) is not constant with deformation; indeed R(α) tends to infinity when α>45° and E11<0.02 which corresponds to a planar deformation state. This behaviour can be interpreted by using a model of Sachs type for tensile tests performed along either the rolling direction or the transverse direction by considering only prismatic slip.
