Abstract
A novel process for permanent magnets fabrication is described : low cost and good energy products are achieved by hot-working cast ingot of NdFeB alloys. Magnetic characterization and microstructural observation reveal that the coercivity mechanisms are essentially similar to those observed in sintered magnets.
