Density-optimized molybdenum alloy

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

This invention presents a new type of molybdenum-based alloy optimized for high temperature and low density, primarily by adding vanadium to a molybdenum-silicon-boron (Mo-Si-B) base. The vanadium addition lowers the overall weight of the alloy (to less than 8 g/cm³) without sacrificing its excellent high-temperature strength, oxidation resistance, and toughness, making it especially suitable for advanced aerospace and turbine applications.

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

• Structural components in aerospace industry, including aircraft and spacecraft parts subjected to high temperatures
• Rotating parts in gas turbines, such as turbine blades and disks
• High-performance components in power generation equipment operating at elevated temperatures
• Tooling or dies used in forming or forging processes that demands resistance to heat and oxidation
• Automotive components for engines requiring lightweight and heat-resistant materials
• Advanced industrial furnaces and high-temperature reactors

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduced alloy density compared to conventional Mo-Si-B alloys, enabling weight savings in applications where mass is critical (such as flight or rotation)
• Maintains high-temperature strength and excellent oxidation resistance, crucial for components exposed to extreme environments
• Improved manufacturability through powder metallurgy and additive manufacturing methods, facilitating production of complex or fine-structured parts
• Vanadium addition stabilizes the alloy structure, enhancing the material's toughness and mechanical performance
• Potential to further tailor the material's properties (density, strength, hardness) by adjusting vanadium and optional titanium content
• Reduces or eliminates the need for protective coatings or atmospheres due to inherent oxidation resistance
