Correlation between particle size and magnetic properties in soft-milled Ni45Co5Mn34In16 powders
(Elsevier, 2021)
info:eu-repo/semantics/article,
The effect of microstructural defects induced by mechanical milling has been studied in a Ni–Mn–In–Co metamagnetic shape memory alloy. The martensitic transformation and Curie temperatures do not change with grinding, thus ...
Giant direct and inverse magnetocaloric effect linked to the same forward martensitic transformation
(Springer Nature, 2017)
info:eu-repo/semantics/article,
Metamagnetic shape memory alloys have aroused considerable attraction as potential magnetic
refrigerants due to the large inverse magnetocaloric effect associated to the magnetic-field-induction
of a reverse martensitic ...
Martensitic transformation controlled by electromagnetic field: from experimental evidence to wireless actuator applications
(Elsevier, 2022)
Artículo / Artikulua,
Mechanical actuators based on shape memory alloys (SMA) are becoming a key component in the development of novel soft robotic applications and surgically implantable devices. Their working principle relies in the temperature ...
Routes for enhanced magnetism in Ni-Mn-In metamagnetic shape memory alloys
(Elsevier, 2019)
info:eu-repo/semantics/article,
The authors provide in-depth physical insight into the enhancement of the magnetic properties of metamagnetic shape memory alloys produced by thermal treatment and cobalt doping. They use neutron scattering to study the ...
Influence of structural defects on the properties of metamagnetic shape memory alloys
(MDPI, 2020)
info:eu-repo/semantics/article,
The production of µ-particles of Metamagnetic Shape Memory Alloys by crushing and subsequent ball milling process has been analyzed. The high energy involved in the milling process induces large internal stresses and high ...
Study of the martensitic transition in Ni-Mn-Sn-Ti ferromagnetic shape memory alloys
(Rede Latino-Americana de Materiais, 2018)
info:eu-repo/semantics/article,
In the present work, mechanical spectroscopy measurements as a function of temperature and strain have been performed in (at.%) Ni50Mn37Sn13-xTix (x=0, 0.5 and 2) ferromagnetic shape memory alloys in order
both to study ...
Evolution of magnetic response as a function of annealing temperature in Fe-based alloys
(Rede Latino-Americana de Materiais, 2018)
info:eu-repo/semantics/article,
The magnetic response, coercive force and magnetic induction, in Fe-10at.% Si, Fe-6at.% Al-9at.% Si and Fe-4at.% Al-8at.% Ge alloys as a function of the annealing temperature was determined and correlated to the microstructural ...
Influence of defects on the irreversible phase transition in the Fe-Pd doped with Co and Mn
(Rede Latino-Americana de Materiais, 2018)
info:eu-repo/semantics/article,
The appearance of BCT martensite in Fe-Pd-based ferromagnetic shape memory alloys, which develops at lower temperatures than the thermoelastic martensitic transition, deteriorates the shape memory properties. In a previous ...
119Sn Mössbauer spectroscopy for assessing the local stress and defect state towards the tuning of Ni-Mn-Sn alloys
(AIP Publishing, 2017)
info:eu-repo/semantics/article,
The influence of defects and local stresses on the magnetic properties and martensitic transformation in Ni50Mn35Sn15 is studied at macroscopic and atomic scale levels. We show that both the structural and magnetic properties ...
Analysis of the strain misfit between matrix and inclusions in a magnetically tunable composite
(Elsevier, 2021)
info:eu-repo/semantics/article,
A magnetically tunable composite has been elaborated by embedding microparticles of a metamagnetic shape memory alloy on a photo curable resin. The strain misfit between the polymeric matrix and the inclusions has been ...
