Polvo de aleación de alta entropía 2025: Propiedades, aplicaciones y perspectivas de mercado
Overview of High-Entropy Alloy Powder
High-entropy alloy (HEA) powder is a cutting-edge material composed of multiple principal elements in nearly equal atomic ratios, which results in exceptional mechanical strength, thermal stability, and corrosion resistance. Unlike traditional alloys, which rely on a single dominant element, HEAs leverage the synergy of multiple metals para conseguir superior properties.
Due to their high hardness, excellent oxidation resistance, and outstanding wear resistance, high-entropy alloy powders are extensively used in aerospace, defense, biomedical, energy, and additive manufacturing (impresión 3D).
