Excellent superelasticity in a Co-Ni-Ga high-temperature shape memory alloy processed by directed energy deposition

Materials Research Letters, 2020
A Co-Ni-Ga high-temperature shape memory alloy has been additively manufactured by directed energy deposition. Due to the highly anisotropic microstructure, i.e.

Thermodynamics of Ideal Pseudoelasticity [PDF]

Le Journal de Physique IV, 1995
Experimental results are shown for CuZnAl single crystals which summarize the thermal equation of state of these alloys in the pseudoelastic temperature range, i.e. their (P,d,T)- behaviour. For a partial explanation the first and second law of thermodynamics are applied under the assumption that the essential relevant constitutive ingredients are i ...

Temperature contour maps at the strain-induced martensitic transition of a Cu–Zn–Al shape-memory single crystal [PDF]

, 2011
We study temperature changes at the reverse strain-induced martensitic transformation in a Cu–Zn–Al single crystal. Infrared thermal imaging reveals a markedly inhomogeneous temperature distribution.

Relation between the martensite volume fraction and the equivalent transformation strain in shape memory alloys [PDF]

, 2005
International audienceThis study concerns the pseudoelasticity of shape memory alloys. A series of tests under multiaxial loadings and a micro-macro model are used to show the validity of a conjecture concerning the relation between the volume fraction ...

Study of the formation of Cu-24at.% Al by reactive milling [PDF]

, 2015
In this work, powders of Cu and Al were milled with a proportion equal to 24 atomic % Al, using low and medium energy mills. The initial, intermediate and final stages of the resulting powder are analyzed using scanning electron microscopy, X-ray ...

Large Deformation Constitutive Theory for a Two-Phase Shape Memory Alloy

Engineering Transactions, 2015
In this work we examine significant theoretical issues related to the constitutive modelling of a two-phase shape memory alloy which undergoes large deformations. For this purpose, we propose a new generalized plasticity based model.

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]

, 2012
The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and
