Abstract

This work investigates the influence of small additions of aluminum on the structure of ingots from a high-entropy alloy of the (Fe_0.25Co_0.25Ni_0.25Cr_0.125V_0.125)₈₃B₁₇ composition. The structure of experimental alloys was analyzed using scanning electron microscopy and EDX analysis. The borides formed in the structure were analyzed by transmission electron microscopy, X‑ray diffraction, and electron backscatter diffraction. Aluminum addition was found to change the crystallization process of the alloys, affecting the type of primary boride crystals and eutectic composition. The addition of aluminum to the alloy in greater amounts changes the boride type from refractory boride of (V, Cr)B type to a more easily melting type of boride M₃B₂.

少量添加铝对（Fe0.25Co0.25Ni0.25Cr0.125V0.125）83B17合金组织和相组成的影响

本文研究了少量添加铝对（Fe0.25Co0.25Ni0.25Cr0.125V0.125）83B17高熵合金铸锭组织的影响。采用扫描电镜和EDX分析分析了实验合金的组织。通过透射电镜、X射线衍射和电子背散射衍射分析了结构中形成的硼化物。铝的加入改变了合金的结晶过程，影响了初生硼化物晶体的类型和共晶成分。随着铝的大量加入，硼化物类型从难熔的（V, Cr）B型硼化物转变为更容易熔化的M3B2型硼化物。
