Powder and Wire Metallurgy (PW/M) is a commonplace fabrication and processing method for high throughput part production in industrial settings. Additionally, PW/M fabrication and processing advancement also is an essential counterpart to the advancement of additive manufacturing (AM) with powder-based AM methods. Novel and intensive research is ongoing in innovative, traditional, and emerging magnetic materials and functional materials, however, the practical application is limited by the ability to form these typically brittle materials into the shapes that are designed for the applications. At this time, advanced powder synthesis and processing, including additive manufacturing, can provide a way to form these materials into final shapes for applications.
The purpose of this symposium is to tie both magnetic and functional materials to advanced powder synthesis and additive manufacturing, as well as other advanced processing approaches and discuss aspects such as process-property relationships, functionality, and/or application performance. Magnetic and functional material systems of interest include, but are not limited to:
• Soft magnets (nano-crystalline alloys, high Si-steel)
• Hard magnets (Nd-Fe-B, Sm-Co, MnAlC, MnBi, alnico, ferrite, exchange-coupled)
• Magnetocaloric materials (Gd-Si-Ge, Gd-Ni-X, RE-RE, RE-Al)
• Magnetic Shape Memory Alloys (Ni-Mn-Ga(-X))
• Shape Memory Alloys (NiTi(X), Fe-based, Cu-based)
