Material solution for extreme environments Inconel Alloy MA754 UNS N07754

High temperature performance benchmark of Inconel Alloy MA754 UNS N07754
Y₂O₃ nano-oxide (particle size ≤ 50nm) is introduced through the mechanical alloying process, and the tensile strength is still maintained at 380MPa at 1,100℃, which is more than 2 times higher than that of traditional nickel-based alloys. The unique fiber texture enables it to exhibit excellent creep resistance under axial load (creep rate <1×10⁻⁸/s at 1200℃/100h).
Environmental tolerance.
Advantages of the double oxide film mechanism (surface Cr₂O₃ + inner Al₂O₃): sulfidation corrosion rate is reduced to 0.02mm/year (ASTM G54 standard test), neutron irradiation swelling rate <0.3% (fast reactor working condition simulation data).
Processability optimization
Hot isostatic pressing (150MPa/1200℃) achieves 98.5% theoretical density, reducing machining by 25% compared with the traditional forging process.
Industry application verification
