The National Science Foundation (NSF) awarded a $619,688 Project Grant under the Engineering program (CFDA 47.041) to the Board of Regents of the University of Nebraska, doing business as the University of Nebraska, to conduct research on additive manufacturing (AM) of rare earth permanent magnets. The key objectives of this 3-year project are: (1) designing alloys tailored for the solidification conditions encountered during AM; (2) conducting in-situ studies of the AM process to gain insights into the processing science of complex alloy systems; and (3) fabricating part-level magnets using commercial laser powder bed fusion machines, producing both isotropic and anisotropic grain structures. The project involves collaboration between the University of Nebraska-Lincoln and the Indian Institute of Technology-Kharagpur, aiming to train students in magnetic materials and AM to ensure continued U.S. leadership in these areas. The research aims to achieve a comprehensive understanding of the AM process for rare earth permanent magnets, which are critical components in energy-efficient electric motors.
