Min Fan is focused on how to get non-rare-earth permanent magnetic alloys with high coercivity and energy product by using ball-milling and arc-melting.


Topic: Direct and Inverse Design Optimization of Magnetic Alloys with Minimized Use of Rare Earth Elements

Experimental materials: AlNiCo

With the development of science and technology, the demand for clean energy and transportation and miniaturization of strong magnetic field is increasing, so we need develop high-flux density permanent magnetic materials.

However, excellent permanent magnets mainly base on rare earth elements, which are exorbitant and not abundant in United States. For this reason, we focus on how to get non-rare-earth permanent magnetic alloys with high coercivity and energy product by traditional process, like ball-milling and arc-melting. One type of promising candidates are Alnico alloys which are characterized by a high Tc(about 850oC), moderate maximum energy product at room temperature and low-temperature coefficients for coercivity and induction, so they are widely used in industry. The excellent ferromagnetic properties of AlNiCo are obtained by the shape anisotropy of the Fe-Co bcc phase divided by a spinodal decomposition reaction in specific temperature range (750oC~850oC) under an applied magnetic field.

We will optimize the compositions and processes for the alloys of premium magnetic properties and explain the relationship between microstructure and magnetic properties at the same time.
