Strain Relaxation in Cu-Al-Ni Shape Memory Alloys Studied by in Situ Neutron Diffraction Experiments
; López Echarri, Ángel María; ; Nó Sánchez, María Luisa; Brown, Donald W.; Balogh, Levente; Breczewski Filberek, Tomasz; San Juan Núñez, José María
(American Institute of Physics, 2019-02-28)
In situ neutron diffraction is used to study the strain relaxation on a single crystal and other powdered Cu-Al-Ni shape memory alloys (SMAs) around martensitic transformation temperatures. This work is focused on the ... -
The Influence of Thermal History on the Multistage Transformation of NiTi Shape-Memory Alloys
; López Echarri, Ángel María; Breczewski Filberek, Tomasz; López, Gabriel Alejandro; López Ferreño, Iñaki; Nó Sánchez, María Luisa; San Juan Núñez, José María (MDPI, 2018-04)
The multistage martensitic phase transformation of a polycrystalline NiTi shape-memory alloy (50.3 at. %Ni-49.7 at. % Ti) has been studied by means of calorimetric measurements. After a conventional thermal treatment ... -
Thermal treatments and transformation behavior of Cu–Al–Be shape memory alloys
; ; ; ; ; San Juan Núñez, José María (Elsevier, 2013-11-15)
Among the different Cu-based shape memory alloys, the Cu–Al–Be family exhibits a particular technological interest for intermediate and low temperature applications. In this work we studied the martensitic transformation ... -
Ultrahigh Superelastic Damping at the Nano-Scale: a Robust Phenomenon to Improve Smart MEMS Devices
; Nó Sánchez, María Luisa; ; Breczewski Filberek, Tomasz; López Echarri, Ángel María; Schuh, Christopher A.; San Juan Núñez, José María (Elsevier, 2019-03)
Micro and nano pillars of Copper-based shape memory alloys (SMAs) with feature sizes between about 2 mu m and 250 nm are known to exhibit ultra-high mechanical damping due to the nucleation and motion of stress-induced ...
