Abstract

The phase equilibria in the V-rich region of the V-Si-B system, including the V₈SiB₄ phase, have been experimentally investigated. Eleven alloys with key compositions were produced by arc-melting or levitation-melting. The samples were then annealed at 1400 °C for 100/200/300 h under high vacuum condition. The as-cast and heat-treated alloys were investigated by scanning electron microscopy, electron backscatter diffraction, energy-dispersive x-ray spectroscopy and x-ray diffraction. The isothermal section at 1400 °C of the V-rich V-Si-B system was determined and compared with the one at 1600 °C. The determined isothermal section can be applied to the design of V-Si-B alloys.

1400℃时V-Si-B体系富v区相平衡

实验研究了V-Si-B体系富v区的相平衡，包括V8SiB4相。采用电弧熔炼和悬浮熔炼法制备了11种具有关键成分的合金。然后在1400℃高真空条件下退火100/200/300 h。采用扫描电镜、电子背散射衍射、能量色散x射线能谱和x射线衍射对铸态和热处理合金进行了研究。测定了富V-Si-B体系在1400℃时的等温切片，并与1600℃时的等温切片进行了比较。测定的等温截面可用于V-Si-B合金的设计。

期刊介绍： The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts. The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use. Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
