High-Temperature Alloys
High-Temperature Alloys
High-temperature alloys are materials engineered to withstand elevated temperatures while maintaining their mechanical properties, resistance to oxidation and corrosion, and structural integrity. These alloys are used in extreme environments where materials are subjected to thermal stresses, such as gas turbines, jet engines, and industrial furnaces.
The primary categories of high-temperature alloys include superalloys, heat-resistant steels, and refractory metals. These materials are specifically designed for applications in industries like aerospace, power generation, automotive, chemical processing, and more.
Key Characteristics of High-Temperature Alloys
Thermal Stability
Maintain strength and dimensional stability at elevated temperatures.
Oxidation Resistance
Resist degradation due to high-temperature exposure to oxygen.
Creep Resistance
Resist deformation under mechanical stress at high temperatures.
Corrosion Resistance
Resist degradation in aggressive chemical environments, such as those found in high-temperature combustion gases or chemical reactors.
High Strength
Retain mechanical strength in the face of high thermal and mechanical stresses.
