Abstract:
We present a magneto-thermo-mechanical literature review of Rare-Earth free magnets, focusing on Mn-based binary alloys in relation to their Chemistry-Process-Structure-Property- Performance (CPSPP) relationships. Recent electric performance systems and technologies use Rare-Earth (RE) magnets due to the high magnetic power they provide; however, the limited resources of RE elements in the earth, has pushed the emerging need to identify and understand Mn-based magnetic alloys. Mn is abundant, fairly inexpensive, easily manufacturable, and eco- friendly. Although previous literature reviews included magnetic properties of different RE based and RE free magnets, none of the previous literature reviews related the magnetic properties to the mechanical properties nor did they relate the complete CPSPP relationship. Magnetic and mechanical properties interdependently affect each other with more complexity added under different temperature materials processing and performance environments. The thermomechanical deformation processes impact the multiscale hierarchical structures and the associated magnetic behavior at different size scales (electrons, subgrains, grains, and polycrystals). The magneto- thermo-mechanical properties of Mn-based alloys with a focus on MnAl, MnBi, and MnZn binary alloys and an associated CPSPP map are presented.
