Abstract
The as-received melt spun Cu–40 wt.%Sn ribbon displayed the shape memory effect, which was observed by bending a ribbon and watching how it returns to its original shape upon heating. The temperature at which the melt spun Cu-40 wt.%Sn completely transformed in austenite upon heating was found to be 470 K. The temperature at which the alloy started to transform to martensite upon cooling was 310 K.
