Piezomagnetism in Cr Dopped Fe65Co35 Alloy

Fe-Co alloys have the highest magnetizations among all existing magnetic materials, 2.45 T for the alloy with 35% Co (% by mass). Regarding magnetostriction, the highest magnetostrictions occurs in Co rich Fe-Co alloys. The piezomagnetic behavior of…

Rapport de la mission post-sismique du séisme du 1er Janvier 2024 de Noto (Japon)

Le lundi 1er janvier 2024, la péninsule de Noto, au Japon, a été frappée par un séisme de magnitude MJ 7,6 (Mw 7,5-7,6). L’épicentre se trouve à l’extrémité Nord-Est de la péninsule. Ce séisme a été ressenti avec une intensité JMA égale ou…

Austenite-martensite interfacial patterns and energy dissipation of phase transformation in Ni-Mn-Ga single crystal

The martensitic phase transformation occurs in Shape Memory Alloys (SMA) via the nucleation/propagation of the Austenite-Martensite interface (A-M interface), which is a transition region (domain) between the two coexisting phases. For providing…

Topology Optimization of a Complete Reluctance Machine with no Initial Information on its Geometry

This paper addresses the topology optimization of an entire multiphase reluctance machine. Multiple materials are automatically and simultaneously distributed in the rotor and stator to maximize torque, minimizing the designer bias. As an extension…

Characterization on thermal hysteresis of shape memory alloys via macroscopic interface propagation

A specimen of Shape Memory Alloy (SMA) starts martensitic phase transformation normally by the nucleation of a macroscopic austenite-martensite interface at the specimen's boundary (i.e., the nucleation is sensitive to boundary conditions). By…

Study of REBa2Fe3O8+δ (RE = Pr, Nd, Sm) layered perovskites as cobalt-free electrodes for symmetrical solid oxide fuel cells

The REBa2Fe3O8+δ (RE = Nd, Sm, Pr) perovskites are investigated as potential cobalt-free electrodes in symmetrical solid oxide fuel cells (SOFCs). After the preparation of samples by a soft chemistry route, we first characterized the intrinsic…
