[en] Studies results concerning the ageing of zirconium alloys (zircaloy 2 and 4, Zr Nb alloys, and Zr Fe alloys) and its effects on mechanical properties, are presented: after a review of the static and dynamic ageing phenomena and the Portevin Le Chatelier effect, the case of zirconium-oxygen is more especially examined, with emphasis on the tensile and creep properties: interstitial oxygen appears to be the source of a rapid bonding of dislocations which leads to important effects on mechanical properties. Irradiation effects on ageing are also studied. (A.B.)
