Isothermal Section of the V-Si-B System at 1600 °C in the V-$ VSi_{2} $-VB Region
Abstract In recent years, the Me-Si-B (Me-metal) ternary systems have received considerable attention aiming at the development of high-temperature structural materials. Assuming that any real application of these materials will rely on multicomponent alloys, as is the case of Ni-base superalloys, p...

| 520 | |a Abstract In recent years, the Me-Si-B (Me-metal) ternary systems have received considerable attention aiming at the development of high-temperature structural materials. Assuming that any real application of these materials will rely on multicomponent alloys, as is the case of Ni-base superalloys, phase equilibria data of these systems become very important. In this work, results are reported on phase equilibria in the V-Si-B system, and are summarized in the form of an isothermal section at 1600 °C for the V-$ VSi_{2} $-VB region. Several alloys of different compositions were prepared via arc melting and then heat-treated at 1600 °C under high vacuum. All the materials in both as-cast and heat-treated conditions were characterized through x-ray diffraction, scanning electron microscopy, and selected alloys via wavelength dispersive spectroscopy. A negligible solubility of B in the $ V_{3} $Si, $ V_{5} $$ Si_{3} $ ($ T_{1} $), and $ V_{6} $$ Si_{5} $ phases as well as of Si in $ V_{3} $$ B_{2} $ and VB phases was noted. Two ternary phases presenting the structures known as $ T_{2} $ ($ Cr_{5} $$ B_{3} $-prototype) and $ D8_{8} $ ($ Mn_{5} $$ Si_{3} $-prototype) were observed in both as-cast and heat-treated samples. It is proposed that at 1600 °C the homogeneity range of $ T_{2} $ extends approximately from 5 at.% to 12 at.% Si at constant vanadium content and the composition of $ D8_{8} $ phase is close to $ V_{59.5} $$ Si_{33} $$ B_{7.5} $ (at.%). | ||

Abstract In recent years, the Me-Si-B (Me-metal) ternary systems have received considerable attention aiming at the development of high-temperature structural materials. Assuming that any real application of these materials will rely on multicomponent alloys, as is the case of Ni-base superalloys, phase equilibria data of these systems become very important. In this work, results are reported on phase equilibria in the V-Si-B system, and are summarized in the form of an isothermal section at 1600 °C for the V-$ VSi_{2} $-VB region. Several alloys of different compositions were prepared via arc melting and then heat-treated at 1600 °C under high vacuum. All the materials in both as-cast and heat-treated conditions were characterized through x-ray diffraction, scanning electron microscopy, and selected alloys via wavelength dispersive spectroscopy. A negligible solubility of B in the $ V_{3} $Si, $ V_{5} $$ Si_{3} $ ($ T_{1} $), and $ V_{6} $$ Si_{5} $ phases as well as of Si in $ V_{3} $$ B_{2} $ and VB phases was noted. Two ternary phases presenting the structures known as $ T_{2} $ ($ Cr_{5} $$ B_{3} $-prototype) and $ D8_{8} $ ($ Mn_{5} $$ Si_{3} $-prototype) were observed in both as-cast and heat-treated samples. It is proposed that at 1600 °C the homogeneity range of $ T_{2} $ extends approximately from 5 at.% to 12 at.% Si at constant vanadium content and the composition of $ D8_{8} $ phase is close to $ V_{59.5} $$ Si_{33} $$ B_{7.5} $ (at.%). © ASM International 2009 |
