摘要

Method for substantially improving the resistance of a zirconium-based alloy element to accelerated pustular corrosión that results in the formation of thick oxide layers, characterized in that it includes the phases consisting in heating the element to a temperature at which the phase is at least partially transformed in beta phase, maintaining the element at said temperature to initiate the transformation of alpha phase into beta phase, and then cooling the element and thus precipitating, in the form of particles, in the limits of alpha grains, the intermetallic phase dissolved during the heating phase.
