摘要

本文研究了不超过0.2%的微量铝和锰对高熵合金（Fe0.25Ni0.25Co0.25Cr0.125V0.125）83B17的组织和非晶化倾向的影响。铝和锰的加入影响了铸锭的相组成，抑制了MeB硼化物的结晶，增加了共晶成分的含量。确定了熔体纺丝过程中形成完全非晶结构的最佳添加剂用量。确定了合金结晶过程与熔体纺丝过程中形成非晶结构倾向之间的关系。研究表明，加入钒的非晶多组分合金需要一种特殊的方法，因为钒作为内部的氮吸收剂，形成难熔的氮化物颗粒。结果表明，在母合金生产过程中，形成的难熔颗粒是结晶中心，使得熔体纺丝过程中难以获得单一的非晶态。

Influence of minor refining additives Al and Mn on the amorphous structure formation in the Fe-Co-Ni-Cr-V-B alloy

The paper studies the effect of small additions, not exceeding 0.2 %, of aluminum and manganese on the structure of ingots and the tendency to amorphization of the high entropy alloy (Fe₀_.25Ni_0.25Co_0.25Cr_0.125V_0.125)₈₃B₁₇. The addition of aluminum and manganese affects the phase composition of the ingots, suppressing the crystallization of the MeB boride and increasing the content of the eutectic component. The optimum amount of additives that lead to the formation of a completely amorphous structure during the melt spinning process has been established. The relationships between the alloy crystallization process and the tendency to form an amorphous structure during melt spinning process are determined. The work shows that amorphous multicomponent alloys with the addition of vanadium require a special approach, since vanadium acts as an internal nitrogen getter and forms refractory nitride particles. It is shown that refractory particles, which are crystallization centers, can form during the master alloy production process and make it difficult to obtain a single amorphous state during the melt spinning process.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
