摘要

永磁搅拌（PMS）技术的进步对凝固铝晶粒细化具有重要意义。采用PMS诱导的不同旋转磁场（RMF）方案，对3个纯度等级的铝进行了显微组织和性能演变的对比研究。实验结果表明，使用RMFs可以使凝固铝产生细小均匀的等轴晶粒组织，并且RMFs对晶粒细化的影响很大程度上取决于凝固铝的纯度。硬度和电导率的变化趋势与晶粒尺寸的变化趋势高度相关。讨论了PMS对铝凝固组织演变影响的原因。

Microstructural and performance evolution of solidified aluminum under permanent magnet stirring

The technological progress of permanent magnet stirring (PMS) is of great significance for solidified aluminum grain refinement. A comparative study has been carried out to explore the microstructural and performance evolution of solidified aluminum with three purity grades under various rotating magnetic field (RMF) schemes induced by PMS. The experimental results suggest that the use of RMFs can produce fine and homogeneous equiaxed grain structures of solidified aluminum, and the influence of RMFs on grain refinement strongly depends on the purity level of solidified aluminum. The tendency changes of hardness and electrical conductivity are highly correlated with that of grain size. Moreover, the reasons have also been discussed to explain the effect of PMS on the microstructural evolution of solidified aluminum.

期刊介绍： Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry. The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
