Abstract

Spherical powders of CoCrFeNiMnW0.25 high-entropy alloy were obtained from elemental powders by mechanical alloying (MA) at various energy modes followed by plasma spheroidization. Samples obtained from low-energy MA-powders have an inhomogeneous microstructure and phase composition. Samples obtained from MA-powders with homogeneous structures have a high degree of sphericity and chemical homogeneity; the face-centered cubic solid solution represents the phase composition of the powders. The resulting powders can be used in powder-based additive manufacturing technologies.

机械合金化和等离子球化工艺合成CoCrFeNiMnW 0.25高熵合金粉末的增材制造

摘要

CoCrFeNiMnW 0.25高熵合金的球形粉末是通过在各种能量模式下通过机械合金化(MA)然后进行等离子体球化而从元素粉末中获得的。从低能MA粉获得的样品具有不均匀的微观结构和相组成。从具有均匀结构的MA粉中获得的样品具有很高的球形度和化学均质性。面心立方固溶体代表粉末的相组成。所得粉末可用于基于粉末的增材制造技术中。
