Abstract
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 (Fe0.25Ni0.25Co0.25Cr0.125V0.125)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.
