The determination and evaluation of Nitinol constitutive models for finite element analysis [PDF]

, 2007
Superelastic Ni-Ti (Nitinol) is a member of the shape memory alloy (SMA) family of metals. The physical properties of Nitinol are highly dependant on a number of factors, including manufacturing method, subsequent processing, operating temperature, and ...

Electropolishing parameters of NiTi alloy

Transactions of Nonferrous Metals Society of China, 2006
Abstract Electropolishing has been used in NiTi alloy in several fields for its special characteristics, but its essential details and electropolishing mechanism have not been reported yet as a demand from business competition, which, to a great degree, restricts the application and extension of the electropolishing technology.

Shape Memory Behavior of Porous NiTi Alloy

Metallurgical and Materials Transactions A, 2016
Shape memory behavior of porous NiTi alloy is dependent on the phases, and mechanical or thermal background. The phases change with solution heat treatment and aging. Fully reversible shape memory behavior was observed during thermal cycling, and recoverable strains increased with the increasing stress from 2 to 50 MPa.
