Monitoring structural transformations in metamagnetic shape memory alloys by non-contact GMI technology
(IOP Publishing, 2023)
Artículo / Artikulua,
Different applications based on metamagnetic shape memory alloy (MSMA) require monitoring the evolution of the martensitic transformation (MT) to optimize the actuation mechanism. To avoid interaction with the active ...
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 ...
Magnetically tunable damping in composites for 4D printing
