Particle-Reinforced High-Temperature Material

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

This patent describes a novel high-entropy alloy (HEA) material, primarily composed of iron, aluminum, copper, nickel, and titanium (each between 10% and 50% atomic fraction), possibly with small amounts of other elements. The key innovation is a particle-reinforced microstructure that remains stable and retains high hardness and compressive strength even at elevated temperatures up to 1200°C, while minimizing density compared to existing high-strength HEAs. The material and its manufacturing process result in a lightweight, heat-resistant alloy suitable for high-stress environments.

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

• Aerospace components (e.g. turbine blades, structural airframe parts) requiring high strength at high temperatures with reduced weight.
• Automotive engine parts or exhaust system components exposed to prolonged high temperatures.
• Industrial furnaces, power plants, or chemical reactor components where materials must resist deformation and oxidation at extreme temperatures.
• Tooling for metal forming, extrusion, or die casting, where hot strength and wear resistance are vital.
• Additive manufacturing (3D printing) of custom, high-performance metal components for demanding applications.

BenefitsContent extracted from patent full text and abstract with AI.

• High temperature stability and phase integrity up to at least 1200°C, reducing failure risk under thermal stress.
• Lower density compared to other high-strength alloys, enabling lighter structures and improved efficiency.
• Very high hardness (Vickers hardness > 650 HV) and compressive strength across a broad temperature range, which translates to durability and wear resistance.
• Resistance to phase transformations and oxidation at operational temperatures, leading to longer material life in harsh environments.
• Flexible composition allows for further optimization towards ductility and toughness by minor additions of B or Zr, or enhanced stability with other transition metals.
• Manufacturing methods compatible with conventional melting, powder metallurgy, and additive manufacturing, supporting a wide range of industrial processes.
