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.
German scientists at Saarland University have produced a prototype machine that transfers heat using a nickel-titanium ("nitinol") alloy wire wrapped around a rotating cylinder. As the cylinder rotates, heat is absorbed on one side and released on the other, as the wire changes from its "superelastic" state to its unloaded state.
NiTiNOL 60, or 60 NiTiNOL, is a Nickel Titanium alloy (nominally Ni-40wt% Ti) discovered in the late 1950s by the U. S. Naval Ordnance Laboratory (hence the "NOL" portion of the name NiTiNOL). [1] Depending upon the heat treat history, 60 NiTiNOL has the ability to exhibit either superelastic properties in the hardened state or shape memory ...
Shape-memory coupling is a system for connecting pipes using shape-memory alloys.In its typical form the technique uses an internally ribbed sleeve of alloy such as Tinel(see Nitinol) that is slightly smaller in diameter than the pipes it is to connect.
George F. Andreasen (February 16, 1934 – August 11, 1989), born in Fremont, Nebraska, was an American orthodontist and inventor.. Andreasen, most noted for his invention and patent of the Nitinol Wire, also known as Memory Wire or shape memory alloy, began his experimentation with the nickel-titanium (NiTi) alloys as early as 1969.
President-elect Donald Trump has said he might install his picks for top administration posts without first winning approval in the U.S. Senate. This would erode the power of Congress and remove a ...
His medical event isn’t an isolated one. Hamlin spent several days in critical condition in the intensive care unit at the University of Cincinnati Medical Center after collapsing during a game ...
Nitinol biocompatibility is an important factor in biomedical applications. Nitinol (NiTi), which is formed by alloying nickel and titanium (~ 50% Ni), is a shape-memory alloy with superelastic properties more similar to that of bone, [ clarification needed ] when compared to stainless steel , another commonly used biomaterial .
