This study explores a new concept of the synergy between two constituent shape memory alloys (SMAs) in composite to achieve wide superelastic temperature window. In this work, nanocrystalline NiTi/NiTiNbFe dual-SMA is designed, which SMAs are both capable stress-induced martensitic transformation, but within different ranges. Based on principle lattice strain matching SMAs, transformation one i...

The properties and cost have made the Nickel-Titanium (NiTi) shape memory alloys (SMA) attractive for a variety of applications wherein shape memory effect (SME) / superelasticity (SE) and biocompatibility are important. Anisotropy of the shape recovery associated with shape memory effect strongly depends on the type of r 30 minutes in air) Ti-Rich Ni-Ti SMA (Ni51at%Ti) when subjected to cold r...
