摘要

本文成功地采用机械合金化法制备了FeNiMnCuX (X: Co, Cr, Mo, Ti, W)高熵合金。磨矿15h后，FeNiMnCu和FeNiMnCuCo合金形成单一FCC结构，其他合金形成FCC + BCC混合结构。所有合金均含有均匀分布的Fe和Ni，而Cu是偏析的。FeNiMnCuTi和FeNiMnCuW合金Mn呈均匀分布，而其他合金则呈富锰岛状分布。除FeNiMnCuTi合金外，所有合金均表现出软磁行为。添加Co可提高FeNiMnCu基合金的饱和磁化强度，添加Cr、Mo、Ti和W可降低FeNiMnCu基合金的饱和磁化强度。

Alloying, phases and magnetic behaviour of mechanically alloyed FeNiMnCu-based high entropy alloys

In the present work, FeNiMnCuX (X: Co, Cr, Mo, Ti, W) high entropy alloys are successfully fabricated by mechanical alloying. After 15 h of milling, FeNiMnCu and FeNiMnCuCo alloys form a single FCC structure, while other alloys formed an FCC + BCC mixture structure. All alloys contained homogeneous distributions of Fe and Ni, while Cu was segregated. Alloys FeNiMnCuTi and FeNiMnCuW exhibited homogeneous distributions of Mn, whereas others exhibited Mn-rich islands. Except for the FeNiMnCuTi alloy, all alloys exhibited a soft magnetic behaviour. The saturation magnetisation of the base FeNiMnCu alloy was increased by adding Co and decreased by adding Cr, Mo, Ti, and W.
