Influence of intermartensitic transitions on transport properties of Ni2.16Mn0.84Ga alloy

, 2004
Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent ...

Oxidation Kinetics of a NiPtTi High Temperature Shape Memory Alloy [PDF]

, 2007
A high temperature shape memory alloy (HTSMA), Ni30Pt50Ti, with an M(sub s) near 600 C, was isothermally oxidized in air for 100 hr over the temperature range of 500 to 900 C. Parabolic kinetics were confirmed by log-log and parabolic plots and showed no

Shape memory effect of NiTi alloy processed by equal-channel angular pressing followed by post deformation annealing

, 2014
Processing by Equal-Channel Angular Pressing (ECAP) is generally considered superior to most other SPD techniques because it uses relatively large bulk samples.
