Emissivity measurements conducted on intermetallic γ-TiAl-based alloys for aeronautical applications
; ; Echániz Ariceta, Telmo
; ; ; ; López, Gabriel Alejandro (Elsevier, 2023-11)
The directional spectral emissivity of a Ti–48Al–2Nb–2Cr alloy (in at.%), 4822 alloy, and a Ti-43.5Al–4Nb–1Mo-0.1B alloy (in at.%),TNM alloy, used in the aeronautical industry, are measured between 150 and 850 °C. The ... -
High-pressure torsion driven phase transformations in Cu-Al-Ni shape memory alloys
; ; López, Gabriel Alejandro; ; ; San Juan Núñez, José María ; ; (Elsevier, 2016-12-16)
Severe plastic deformation (SPD) frequently induces phase transformations like decomposition of supersaturated solid solution, dissolution of precipitates, amorphization, nanocrystallization etc. Such diffusive phase ... -
Precise spectral directional infrared emissivity of a Cantor high-entropy alloy
; ; ; ; ; ; Echániz Ariceta, Telmo (AIP, 2024-07-11)
The multicomponent equiatomic CrMnFeCoNi alloy was proposed by B. Cantor almost 20 years ago and was the first in the family of so-called multiprincipal or high-entropy alloys (HEAs). Various mechanical properties of the ... -
Size-effect and scaling power-law for superelasticity in Shape Memory Alloys at the nano-scale
; ; ; ; ; ; San Juan Núñez, José María (Macmillan Publishers Limited, part of Springer Nature., 2017-05-29)
Shape-memory alloys capable of a superelastic stress-induced phase transformation and a high displacement actuation have promise for applications in micro-electromechanical systems for wearable healthcare and flexible ... -
Stress-assisted atomic diffusion in metastable austenite D03 phase of Cu-Al-Be shape memory alloys
López Ferreño, Iñaki; Breczewski Filberek, Tomasz; López, Gabriel Alejandro; Nó Sánchez, María Luisa; San Juan Núñez, José María (Pergamon-Elsevier, 2016-11)
Cu-Al-based shape memory alloys are firm candidates to be used up to 473 K. The main limiting aspect is the activation of diffusion processes in the metastable austenite phase, which drive the alloy decomposition. In 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 ...
