Processing materials under magnetic fields is an underexplored technique to improve structure and mechanical properties in metals and alloys. Magnetic fields can alter phase stability, modify diffusion characteristics, and alter material flow substantially. In castings, magnetic fields can be used during melting of the alloy, during solidification, or during postprocessing operations such as heat treatment to achieve structural changes. This work investigates the effectiveness of thermomagnetic processing during heat treatment of Al alloys containing in the Al–Cu, Al–Si–Cu, and Al–Mg–Ce systems. We demonstrate an improvement in mechanical properties and a reduction in required heat treatment times for all alloys.

在磁场下加工材料是提高金属和合金的结构和机械性能的探索技术。磁场会改变相稳定性，改变扩散特性，并显着改变材料流动。在铸件中，可以在合金熔化过程中，凝固过程中或在后处理操作（例如热处理）中使用磁场以实现结构变化。这项工作研究了在Al-Cu，Al-Si-Cu和Al-Mg-Ce系统中所含铝合金的热处理过程中热磁处理的有效性。我们证明了所有合金的机械性能都有所改善，并减少了所需的热处理时间。
