The functionality of NiTiHf (25%Hf) shape memory alloy (SMA) was studied under isobaric temperature cycling experiments. Both the local and overall strains, determined with digital image correlation (DIC), displayed excellent stability and no measurable unrecovered elongation. The external stress levels were higher than 250 MPa and transformation temperature was 420 °C which exceeds other NiTi based alloys, demonstrating the outstanding potential of the NiTiHf alloys.

Abstract
The functionality of NiTiHf (25%Hf) shape memory alloy (SMA) was studied under isobaric temperature cycling experiments. Both the local and overall strains, determined with digital image correlation (DIC), displayed excellent stability and no measurable unrecovered elongation. The external stress levels were higher than 250 MPa and transformation temperature was 420 °C which exceeds other NiTi based alloys, demonstrating the outstanding potential of the NiTiHf alloys.File in questo prodotto:
