摘要

作为非稀土磁性材料的铁磁性α-锰硼相越来越受到人们的关注，但制造含有大量α-锰硼的大体积磁体仍是一项挑战......本文介绍了一种由多步严重塑性变形和磁场退火组成的新型固态加工路线，为加工不含稀土的块状磁体开辟了一条新途径。

Multistep severe plastic deformation to achieve non-rare earth bulk magnets with high α-MnBi phase content

The ferromagnetic α-MnBi phase as non-rare earth magnetic material has gained increasing interest, but the fabrication of large volumes containing a significant amount of α-MnBi is still challengin...A novel solid-state processing route consisting of multistep severe plastic deformation and magnetic field annealing is presented, which opens a new pathway for processing rare-earth free bulk magn...

期刊介绍： Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
