Webb9 nov. 2016 · An experimental investigation into microscale transformation characteristics of polycrystalline NiTi wires of 500 µm diameter during shape memory cycling is discussed, with emphasis on the characterization of a pronounced heterogeneity in the strain distribution evident during detwinning of the martensite phase upon application of … Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Different alloys are named according to the weight percentage of nickel; e.g., Nitinol 55 and Nitinol 60. It exhibits the shape memory effect and superelasticity at … Visa mer The word Nitinol is derived from its composition and its place of discovery: (Nickel Titanium-Naval Ordnance Laboratory). William J. Buehler along with Frederick Wang, discovered its properties during research at the Visa mer Nitinol's unusual properties are derived from a reversible solid-state phase transformation known as a martensitic transformation, between two different martensite crystal phases, requiring 10,000–20,000 psi (69–138 MPa) of mechanical stress. Visa mer Fatigue failures of nitinol devices are a constant subject of discussion.
