TEMPERATURE AND STRESS DEPENDENCE OF THE SHAPE MEMORY EFFECT PRODUCED BY ALLOYING ADDITIONS IN Cu-Al-Ni ALLOYSM.A. MORRIS
Institute of Structural Metallurgy, Avenue de Bellevaux 51, University of Neuchâtel, CH-2000 Neuchâtel, Switzerland
The effect produced on microstructure and properties of CuAlNi alloys by additions of elements such as manganese and boron have been studied. Ductilities between 4-6% at room temperature and 12-16% at high temperature (250-300°C) have been achieved. These high strains were produced in all cases by the formation of stress-induced martensite variants which are favourable to produce maximum elongation at each temperature.
