Correlation between anisotropic fractal dimension of fracture surface and coercivity for Nd-Fe-B permanent magnets

Correlation between anisotropic fractal dimension of fracture surface and coercivity for Nd-Fe-B permanent magnets

In this work, SEM images analysis and fractal dimension calculations are performed on the fracture surfaces for N50-type with low coercivity, 30 EH-type with high coercivity, and isotropic Nd-Fe-B permanent magnets. It is discovered for the first time that the difference between the fractal dimensio...
