Abstract
As-spun Ti-rich Ti50.9Ni48.9Si0.2 ribbon showed recoverable superelastic strain of 4.5%, which was associated with elastocaloric cooling of 11.3 K. Cyclic superelastic tests showed that the ribbon exhibited great functional stability. The experimental results demonstrated that the melt-spinning process could improve the functionality of TiNi shape memory alloy.
