20-57 OBŢINEREA PULBERILOR Cu – Zn – Al PRIN PULVERIZARE DIN FAZĂ LICHIDĂ UTILIZATE PENTRU REALIZAREA MATERIALELOR CU MEMORIA FORMEI,
TECHNOLOGY OF OBTAINING ALLOYS
Cu – Zn – Al THROUGH BY SPRAYING OF LIQUID PHASE FOR
MAKING MATERIALS WITH SHAPE MEMORY
Alloys Cu – Zn – Al with shape memory are part of special class of
suitable material, as they can transform heat directly into mechanical work. The
known shape memory alloys, used alloys with the Cu presents some
advantages such as lower cost price, compared with other alloy for example,
high values of shape memory characteristics and capacity of this effect memory
to form after a relatively short period of education. Shape memory alloys are
characterized by a mechanical memory, memory that is due to thermoelastic
behavior.
