Vanadium Alloys Which Are Resistant to Oxidation for Components Subjected to High Temperatures

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses a vanadium alloy composed of 2-35 atomic percent silicon and 3-50 atomic percent boron (with the remainder being vanadium), that forms at least one intermetallic phase including vanadium, silicon, and boron. The invention significantly improves resistance to oxidation at high temperatures while maintaining good mechanical strength, making it suitable for use in structural components that are exposed to high temperatures and oxidative environments without the need for protective atmospheres.

Use CasesContent extracted from patent full text and abstract with AI.

• Structural materials for fusion reactors, where components are exposed to high temperatures and must resist oxidation.
• Components for gas turbines, where high thermal and oxidative stability are critical.
• Parts in aerospace and aviation engineering, such as turbine blades or heat shields, that operate under extreme heat and oxidative stress.
• Industrial furnace components and high-temperature processing equipment.
• Energy conversion devices and advanced powerplants requiring material durability at high temperatures.

BenefitsContent extracted from patent full text and abstract with AI.

• Superior oxidation resistance at temperatures up to at least 1,000°C, even in oxygen-rich environments, compared to conventional vanadium alloys.
• High and stable mechanical strength under both high temperatures and pressure, exceeding that of steels, nickel-based, or titanium alloys in this context.
• Eliminates the need for protective gas atmospheres or oxygen-poor environments, simplifying engineering and reducing costs.
• Customizable alloy properties by adjusting silicon, boron, and possibly other alloying element content, allowing tuning for specific requirements.
• Improved longevity, safety, and reliability of high-temperature components due to enhanced form stability and mechanical properties.
