Abstract

High torque, high frequency, electrical motors require soft magnetic materials with low coercivity and high strength, often relying on rare earth elements like Ta in CoFeNi based alloys. Here, a processing pathway for two Ta-free CoFeNi-based alloys is described, with enhanced properties driven through hierarchical multiphase precipitation.
