Abstract

A permanent magnet formed by additively manufacturing magnetic phases and buffer phases is disclosed. The buffer phase(s) may improve performance, enhance mechanical properties and allow the magnet to better tolerate stresses such that defects such as cracking do not occur or are less likely to occur. The buffer phase may be a magnetic or non-magnetic material.
