Abstract
Zirconium, a material principally used in the nuclear industry, is characterized by the existence of two allotropic varieties, the ß phase and the α phase which are b.c.c and h.c.p crystals respectively. The former is found above 1138K and the later below the same critical temperature. The microstructure arises from a bainitic transformation of the ß phase into the α phase. It consists in colonies composed of parallel laths with the same crystallographic orientation; the “lath boundaries” are the planes where the precipitates of betagenic elements (Fe, Cr, Ni) lie. The principal deformation mechanism under uniaxial tension is prismatic slip: three prismatic slip systems <112̄0> (101̄0) can be activated.
