Abstract
The melt spinning technique has been employed to refine the grain sizes of shape memory (marmem) alloys of Cu-Sn, Cu-Al-Ni, Cu-Zn, Cu-Zn-Al, Cu-Zn-Si and Ti-Ni. Ribbons 1-2 mm wide and 30-60 µm thick with grain sizes of up to 20 µm were obtained. Their martensite transformations and mechanical properties were investigated by optical and electron microscopy, X-ray diffractometry, electrical resistance measurements and mechanical tensile tests. Cu-Sn and Cu-Al-Ni ribbons exhibited the best shape memory effect, while Cu-Zn alloys gave different properties from specimen to specimen, because of variable alloy concentration due to vaporization loss of Zn. Good shape memory ribbons have not yet been prepared in Ti-Ni.
