Исследование структуры и функциональных свойств Fe–21Al–Tb сплавов после термомеханической обработки

Abstract

Исследование посвящено анализу микроструктуры, демпфирующей способности и магнитострикции сплава Fe–21Al, легированного Tb. Термомеханическая обработка обеспечивает повышенную магнитострикцию в сплаве Fe–21Al–Tb. Максимальную величину магнитострикции наблюдали после горячей прокатки и последующего отжига при 900 °C (30 мин) с последующим охлаждением на воздухе. Добавка Tb увеличивает низкотемпературный фон внутреннего трения и магнитострикцию сплавов Fe–21Al–Tb.

The current research focuses on the microstructure, damping capacity, and magnetostriction of the Fe–21Al–Tb. The thermomechanical treatment provides enhanced magnetostriction. The maximum magnetostriction was observed after hot rolling and further annealing at 900 °C with air cooling. The addition of Tb increases magnetostriction and low-temperature internal friction background in Fe–21Al–Tb alloys.

The study was funded by presidential grant no. 075-15-2021-334 (internal number mk-2828.2021.4). The authors expresses their gratitude to the scientific advisor — doctor of physical and mathematical sciences, professor I.S. Golovin.
