Advanced Machining Technology for Active Materials

研究加工方法对磁性材料表面完整性和电性能的影响。该研究旨在调查机械加工（例如机械去除-水射流和剪切和热去除-激光和电火花加工）对软磁材料表面完整性和电性能的影响机制。这将包括通过SEM， EBSD， TEM和微观力学分析来了解冶金变化（例如晶体取向，相变和应力条件）以及影响磁性能的机制。通过机械（水射流、剪切）和热（激光、电火花加工）加工方法，研究高脆性硬磁材料的可加工性。研究加工效应引起的晶体学变化（晶间GB相以及晶体向易磁化轴的排列）及其对磁性能的影响。

To investigate the effects of machining method on the surface integrity and electrical properties of magnetic materials.The research seeks to investigate the mechanisms by which the effects that machining (e.g. Mechanical removal - Waterjet and shearing and thermal removal - Laser and EDM) has on the surface integrity and electrical properties of soft magnetic materials. This will include analysis through SEM, EBSD, TEM, and Micro-mechanics to understand the metallurgical changes (e.g. Crystallographic orientations, phase transformations, and the stress conditions) and the mechanisms that are of influence to the magnetic properties.The research seeks to investigate the machinability of hard magnetic materials which of high brittleness through the mechanical (Waterjet, shearing) and thermal (Laser, EDM) machining methods. To investigate the crystallographic changes (intergranular GB phases as well as crystal alignment to the easy axis of magnetisation) from the machining effect and their influence to the magnetic properties.
