TLDR
In this paper, the thermomechanical properties of the shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of a TiNi shape memory alloy were investigated experimentally.Abstract:
The thermomechanical properties of the shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of a TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformation were excellent for deformation with high cycles.read more

A review on shape memory alloys with applications to morphing aircraft
TL;DR: Shape memory alloys (SMAs) as discussed by the authors are a unique class of metallic materials with the ability to recover their original shape at certain characteristic temperatures (shape memory effect), even under high applied loads and large inelastic deformations, or to undergo large strains without plastic deformation or failure (super-elasticity).

Effect of Cyclic Deformation on the Pseudoelasticity Characteristics of Ti-Ni Alloys
TL;DR: In this article, the authors investigated the change in the pseudoelasticity characteristics of Ti-Ni alloys during tension cycling and concluded that the cause for the effect of cyclic deformation is the generation of dislocations in the martensitic phase.

Mechanical behaviour associated with the premartensitic rhombohedral-phase transition in a Ti50Ni47Fe3alloy
Shuichi Miyazaki,Kazuhiro Otsuka +1 more
TL;DR: In this paper, the mechanical behavior of a Ti50Ni47Fe3 alloy was studied systematically using tensile tests over a wide temperature range covering M s to above T R. Two-stage yielding was observed in the temperature range between M f and a critical temperature, denoted by T X(T X > T R).

NiTi fatigue behavior
TL;DR: In this paper, it was shown that the cycles to failure for NiTi are related exponentially to cyclic strain extent to at least 2×105 cycles, which is insensitive to thermodynamic cycle type or to stress/strain mode, but does show strong dependence on NiTi martensite transition temperature.
