Shape memory effect of nitinol
Webb10 sep. 2024 · Nickel-titanium (NiTi) shape memory alloys (SMA) are widely being used as medical implants due to their excellent shape memory effect (SME) and super-elasticity (SE). The medical implants such as artificial knee joint are usually fabricated by mechanical milling operations. WebbFor a monoclinic martensitic material such as Nitinol, the monoclinic phase has lower symmetry which is important as certain crystallographic orientations will accommodate higher strains compared to other orientations when under an applied stress.
