Abstract (en)
[origin: WO8102587A1] The fine particle memory alloy, of the Cu/Zn/Al, obtained in a high `ss temperature phase, is prepared by powder metallurgy technique and comprises dispersoids in the shape of Y<u2>uO<u3>u - et/or TiO<u2>u - particles which are introduced in the matrix and prevent grain growth. The preparation is carried out by using a mechanical alloying.
