The unique and diverse nanostructures produced by mechanical alloying and subsequent densification by spark plasma sintering are investigated for soft magnetic Fe-Si alloys. The goal of the study is to investigate the processing-structure-properties relationships with a focus on grain refinement, phase evolution and defect dynamics. Mechanical alloying with high energy SPEX ball milling produces nanograined powder with structures that depend on alloy content and processing conditions such as; milling time, ball load, and milling temperature. Spark plasma sintering is used to densify the milled powder while retaining the nano-features. Densification behavior and mechanics are discussed. The fundamental aspects of the magnetic domain-defect interactions and how they affect magnetic properties are proposed.
