Abstract
The workability of hot bending for hot rolled Pr-Fe-B-Cu magnets was investigated. Under optimum bending conditions, Pr-Fe-B-Cu magnets are bent without cracking. The workability is improved at higher temperatures and lower strain rates. The deformation during the bending is derived from the sliding of the grain boundary. Addition of Cu enables the magnets to be worked at a higher strain rate, because of the increased wettability and grain refinement. Arc-shaped magnets were formed by die bending without deterioration of the magnetic properties. Further, radially oriented ring magnets were produced by bonding these magnets with a liquid phase at a high temperature.
