Abstract
The combination of a further developed Equal Channel Angular Swaging (ECAS) process and the subsequent infeed rotary swaging is a promising process chain for the continuous production of permanent magnets. The ECAS process enables a grain refinement as well as an induction of high defect densities in materials. Both effects lead to a higher coercive field strength. In comparison to other SPD-processes lower forming forces are needed and a continuous production is possible. Highly textured magnetically anisotropic samples are realized by a subsequent infeed rotary swaging process.
