(FR) ALLIAGES A MEMOIRE A BASE DE CUIVRE, ZINC ET ALUMINIUM ET PROCEDE POUR LEUR PREPARATION
Abstract: front page image
(EN)The fine particle memory alloy, of the Cu/Zn/Al, obtained in a high (Beta) temperature phase, is prepared by powder metallurgy technique and comprises dispersoids in the shape of Y2O3 - et/or TiO2 - particles which are introduced in the matrix and prevent grain growth. The preparation is carried out by using a mechanical alloying.
