This study focuses on the effect of replacing molybdenum with vanadium in rapidly quenched quasi-high-entropy alloys. The paper analyzes the effect of different boron content levels on structure formation, characteristic temperatures, and mechanical properties. X-ray diffraction and scanning electron microscopy methods were used to establish structural dependencies, and it is suggested that the addition of vanadium leads to the formation of vanadium nitrides in the structure and an increase in thermal stability.
This study focuses on the effect of replacing molybdenum with vanadium in rapidly quenched quasi-high-entropy alloys of the Fe-Co-Ni-Cr-(Mo,V)-B system. The paper analyzes the effect of the chemical composition of alloys with different boron content levels on structure formation, characteristic temperatures of alloys, and mechanical properties. An analysis of the relationship between the structure of alloys and their properties is performed. X-ray diffraction and scanning electron microscopy methods were used in the work to establish the structural dependencies. Characteristic temperatures were determined by differential scanning calorimetry. It is suggested that the addition of vanadium to the alloys of this system leads to the formation of vanadium nitrides in the structure, due to the binding of dissolved nitrogen. Furthermore, it is found that replacing molybdenum with vanadium leads to an increase in the thermal stability of the amorphous phase.
