ALLOY718 superalloy

ALLOY718 superalloy is a solid solution strengthened nickel-based superalloy. Its chemical composition mainly includes nickel, chromium, molybdenum, niobium and other elements. Among them, nickel element is the matrix element and can provide good oxidation resistance and corrosion resistance; chromium element can improve the oxidation resistance and corrosion resistance of the alloy; molybdenum element can improve the strength and creep performance of the alloy; niobium element can Refine the grains and improve the strength and toughness of the alloy.

The structure of ALLOY718 superalloy is mainly composed of phase and phase. Among them, the phase has a face-centered cubic structure and is the main load-bearing phase; the phase has a body-centered cubic structure and mainly plays a strengthening role. In addition, the alloy also contains a certain amount of TCP phase (topological close-packed phase), which is an ordered topological structure that can improve the creep performance of the alloy.

1. Excellent high temperature performance
2. Excellent mechanical properties
3. Good processing performance
