  • Publication number: 20250084511
    Abstract: A Mn—Al—Ti permanent magnet includes a body composed of an alloy consisting essentially of manganese in an amount of 50 to 56 atomic percent, aluminum in an amount of 44 to 50 atomic percent, and titanium in an amount of 0.5 to 1.5 atomic percent with a total amount of manganese, aluminum, and titanium not exceeding 100 atomic percent. In one preferred embodiment, a composition for the Mn—Al—Ti permanent magnet is Mn54Al45Ti1 with substantially no other elemental additions being present. The addition of titanium in amounts of approximately 1 atomic percent to the Mn—Al system is believed to result in the titanium sitting on the anti-phase boundary (APB) sites with atoms coupling ferromagnetically across the APB in the presence of titanium, resulting in suppression of the negative effects of the APB and improving the remanence over a titanium-less Mn—Al permanent magnet. This system also exhibits sustained coercivity at high temperatures.
