The martensitic phase transition and exchange bias effect of the Ni-Mn-based ferromagnetic shape memory alloys (FSMAs) Ni45Co5Mn37In13 (Ni-Co-Mn-In) films are investigated in this paper. transformation properties Ni-Co-Mn-In alloy target material manipulated by process electric arc melting, melt-fast quenching, high-temperature thermal pressure. with martensite characteristics obtained adjustin...

A common problem with space suit systems is overly rigid gloves that resist astronaut finger motion and gripping. In this paper, the design of a mechanism is considered that exploits the small-scale nature of shape memory alloys for actuating glove fingers to assist hand gripping. The design problem is introduced by considering the objectives, constraints, and variables relevant to a spacesuit ...

In this article, a microstructural model of the Heusler alloy with shape memory effect caused by application an external magnetic field is constructed. The dynamics magnetization process are described using Landau–Lifshitz–Gilbert equation. For numerical implementation finite element method, variational equations corresponding to differential formulation problem used. Such approach makes it pos...

A micromechanics approach is proposed to calculate the stress-strain relationship of a polycrystalline Fe-Pd ferromagnetic shape memory alloy. It is modeled as consisting of spherical grains, which are grouped according to their orientations with respect to the loading axis. Therefore, the internal stress and elastic energy are accumulated as straining proceeds due to the strain differences bet...
