Bend-free recovery method to test the shape of nickel-titanium
Memory alloy phase transition temperature
1 Scope
This standard specifies a test method for determining the transformation temperature of martensite to austenite by measuring the deformation recovered during the thermal conversion process.
This standard applies to nickel-titanium alloys that are fully annealed or heat-treated.
Note. This standard is not an attempt to explain all the safety issues involved, even those related to its use. Establish proper safety and
Health regulations, as well as the applicability of clear management restrictions prior to application, are the responsibility of the users of this standard.
