Research Interests:

 The newest Nd-Fe-B permanent magnets have superior magnetic properties than other magnetic materials at room temperature. Thus, they have become very popular in many applications, gradually replacing ferrite- and Sm-type magnets.

Nowadays, the Nd-Fe-B magnets are based on the hard Nd2Fe14B phase with  sintered magnets, a typical starting composition of Nd15Fe77B8 (at %), known as the “Neomax”. This composition is commonly used to develop new magnet processing technologies and to improve magnetic properties. Shifting the alloy composition closer to the Stoichiometric Nd11.8Fe82.3B5.9 phase in the material can increase the magnetic properties. However, this produces the conventionally cast stoichiometric type alloys that contains large amounts of freeα-Fe dendrites, dispersed in the Nd2Fe14B matrix phase. The free α-Fe is a soft magnetic phase and therefore has a deleterious effect on the permanent magnetic properties.  

This project will begin with a systematic investigation of the composition of conventional cast ingot. It will examine the mechanism of the alloys and the effect of ZrB2 on grain size and phase distribution. The ultimate goal of this project is to characterize the mechanism involved in removing the free α-Fe within ZrB2 –containing Nd-Fe-B alloys with Transmission Electron Microscopy
