2. Chemical Composition and Strengthening Mechanisms of Incoloy 901 Stud Bolt
The high-temperature performance of the Incoloy 901 Stud Bolt is primarily due to its composition, which includes nickel, chromium, titanium, aluminum, molybdenum, and niobium. Nickel and iron form the alloy matrix, providing high-temperature strength and stability. Chromium forms a dense Cr₂O₃ oxide layer at high temperatures, effectively preventing further oxidation and corrosion. Titanium and aluminum strengthen the alloy by forming γ' phase (Ni₃(Al,Ti)), significantly enhancing high-temperature strength and creep resistance. Molybdenum and niobium further improve mechanical properties through solid solution strengthening.

3. Long-Term High-Temperature Stability of Incoloy 901 Stud Bolt
In long-term high-temperature exposure tests, the Incoloy 901 Stud Bolt demonstrates excellent stability. After 5000 hours at 700°C, the reduction rates of tensile strength and yield strength are less than 5% and 6%, respectively, while the elongation rate decreases by less than 8%. The oxidation weight gain is only 3.2 mg/cm², indicating the superior protective effect of its oxide layer. Microstructural analysis reveals no significant grain growth or phase transformation, further proving its structural stability in high-temperature environments.
