摘要

磁致伸缩能量收集材料面临的挑战之一是其低发电性能。我们假设在磁化过程中，扭转有利于磁壁的移动，从而提高了铁钴合金丝的磁致伸缩性能。通过自由振动、强制振动和压缩试验，研究了Fe-Co合金绞合丝和Fe-Co合金绞合丝集成环氧树脂基复合材料的反磁致伸缩性能。与最初的假设相反，研究发现，扭转消除了铁钴丝拉丝过程中引入的残余应力。这种应力消除被认为有助于提高磁导率和磁致伸缩。虽然退火提供了类似的好处，但更简单的扭转工艺提供了一个有前途的选择。

Inverse magnetostrictive properties of twisted Fe–Co alloy wire

One of the challenges of magnetostrictive energy harvesting materials is their low power generation performance. We hypothesized that twisting promotes easy movement of the magnetic wall during the magnetization process and improves the magnetostrictive properties of Fe–Co alloy wire. This study evaluated the inverse magnetostrictive properties of twisted Fe–Co alloy wires and the Fe–Co alloy wire integrated epoxy resin matrix composites using free and forced vibration and compressive tests. Contrary to the initial hypothesis, it was found that twisting relieves the residual stress introduced during the drawing of Fe-Co wires. This stress relief is believed to contribute to the improvement in permeability and magnetostriction. While annealing offers similar benefits, the simpler twisting process presents a promising alternative.

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
