Additive Manufacturing of Magnetic Materials: Techniques, Materials, Applications, Opportunities and Challenges (Additive Manufacturing Materials and Technologies)

Additive Manufacturing of Magnetic Materials: Techniques, Materials, Applications, Opportunities and Challenges outlines different 3D printing techniques that can be employed to create an array of different magnetic materials, along with how these materials can be effectively applied. The book discusses the additive manufacturing (AM) of soft magnets, permanent (hard) magnets, 4D magnetic shape memory alloys, magnetocaloric materials, and rare earth based magnetic alloys. Different AM techniques are covered, including laser powder bed fusion, directed laser deposition, binder jetting, cold spray, and the different influences of these techniques on the microstructure of the material produced.

Common challenges are highlighted with solutions also provided, and applications covered include magnetic shielding, actuators, sensors, robotics, and magnetic heat exchangers for solid state heat pumps.

• Presents various additive manufacturing techniques, the different types of magnetic materials produced, and their applications
• Discusses soft and permanent (hard) magnets, 4D magnetic shape memory alloys, magnetocaloric materials, and rare earth based magnetic alloys
• Highlights the common microstructural defects associated with different manufacturing techniques
• Covers applications such as magnetic shielding, actuators, sensors, robotics, and magnetic heat exchangers for solid state heat pumps

Professor Moataz Attallah received his PhD in metallurgy and materials science from the University of Birmingham (2007), BSc (highest honours) and MSc degrees from the American University in Cairo (AUC) Egypt, in mechanical engineering, and materials/manufacturing engineering respectively. Following his PhD, Moataz worked as a research fellow at the University of Manchester Materials Science Centre from January 2007, prior to his appointment as a lecturer at the School of Metallurgy and Materials at the University of Birmingham in June 2010.

His research over the past 20 years focuses on developing a metallurgical understanding of the material-process interaction in advanced manufacturing processes (additive manufacturing, powder processing, friction joining, and superplastic forming) of metallic materials, focusing on the process impact on the microstructure and structural integrity development. His research is conducted through research partnerships with the UK Atomic Energy Authority (UKAEA), GKN Aerospace, Rolls-Royce plc, MBDA, European Space Agency (ESA), ITP, Aero Engine Controls, Johnson-Matthey, BAE Systems, TWI, Safran group companies (Safran Power Units and Safran Landing Systems), Meggitt, Honda R&D, IHI Corporation, Prima Power (Italy), M&I Materials, Magnetic Shields Limited, and the Manufacturing Technology Centre (MTC).

He has published over 200 journal and conference papers and 3 book chapters (h-index: 47), in addition to being a co-inventor for 5 patents.

Abdelmoez Hussein has a PhD in material science, from the University of Oviedo, Spain, March 2017. His research has focused on magnetic materials and their applications in magnetic refrigeration and magnetic sensing.

In December 2017, he joined the University of Birmingham, school of Metallurgy and Materials as a research fellow in the advanced materials processing lab (AMPLab) until present. He has led and participated in the development of several 3D printed magnetic devices such as magnetic shielding prototypes for quantum gravity sensors. Another device developed by Dr Hussein and the group is the magnetic refrigerant media. This is in addition to other investigations which are in progress such as NdFeB permanent magnets, NbTi superconductors and shape memory alloys.
