Performance characteristics of high-temperature alloys
1. High temperature strength: Superalloys can withstand extreme heat, maintaining the strength and stability that other metals may weaken, making them an ideal choice for aerospace and power generation.
2. Oxidation resistance: It has good oxidation resistance in high temperature environments, preventing the formation of an oxide layer on the surface of the material.
3. Corrosion resistance: These materials have excellent oxidation and corrosion resistance, ensuring their service life and reliability in harsh chemical or marine environments.
4. Fatigue resistance: They have high tensile strength, yield strength, and fatigue strength, which means they can withstand severe wear without failure.
5. Thermal stability: Able to maintain structural and performance stability at high temperatures.
6. Good surface stability: High temperature alloys can maintain their surface integrity under high mechanical stress and high thermal cycling, thereby reducing maintenance requirements.
