Microstructure and Performance of Mn-Ga/Fe-Cr-Co Magnetic Composites Fabricated by Mechanical Alloying
Mn-Ga and Fe-Cr-Co have potential use as components in exchange-coupled composite magnets. Herein, we prepared Mn-Ga composites through mechanical alloying, which was followed by sintering. During high-energy ball milling, Fe-Cr-Co powder was added into the Mn-Ga powder to form a composite. The main...

| description | Mn-Ga and Fe-Cr-Co have potential use as components in exchange-coupled composite magnets. Herein, we prepared Mn-Ga composites through mechanical alloying, which was followed by sintering. During high-energy ball milling, Fe-Cr-Co powder was added into the Mn-Ga powder to form a composite. The main phases in the composites existed as pure Mn and pure Ga in the as-milled state; subsequently, these phases changed into intermetallic compounds, such as Mn
