Coercivity Enhancement And Gamma Phase Avoidance Of Alnico Alloys, Li Zhang
Department of Engineering Mechanics: Dissertations, Theses, and Student Research
The promotion of social progress requires greater levels of energy efficiency, quality and productivity. However, these developments usually come at the cost of the environment. Green technologies such as electric vehicles, wind turbine and solar panels are ironically overshadowed by supply limitations and high prices of rare earth elements. Therefore, it is important to find alternative materials to replace those that contain critical elements. Alnico alloys show high magnetization, high Curie temperature (800°C) and good corrosion resistance, making it one of the best candidates to replace neodymium-based magnets used in electric vehicles.
In this thesis, methods controlling shape anisotropy and …
