Ausforming and Marforming of Cu-Zn26.3-Al3.9 Shape Memory Alloy

A copper-based shape memory alloy with M_s below ambient temperature is investigated in four different coditions: 1. As betatized. 2. Ausformed at 800 °C and at 780 °C, subsequrntly quenched. 3. Marformed by different amounts of true plastic deformation at temperatures below M_f. 4. Mechanically cycled (ausformed and as betatized state). The stress amplitudes delta sigma_alfa are chosen in the range between pseudo yield stress R_pp and conventional yield stress R_p0.2 (R_pp
