Nickel-based superalloys superalloy is one, but it has become the most widely used high-temperature strength up to a class of alloys, which are its special composition and performance decisions. Does anyone know of nickel-base superalloys which contain ingredients in the end?

Elemental nickel base alloy contains much dozen different elements of the role are different, such as Cr to play a role in anti-oxidation and corrosion resistance, other elements to strengthen the role of the main. Also we have to strengthen the role, but in practice the way they are different, such as tungsten, molybdenum, cobalt, chromium and vanadium belonging to solid solution strengthening element; aluminum, titanium, niobium and tantalum are precipitation strengthening element; as well as grain boundary strengthening element boron, zirconium, magnesium and rare earth elements.
It is precisely because so many elements of the structure in place, which makes the performance of nickel-based superalloys can be further improved, precision casting out all aspects of high-temperature alloy castings by vacuum induction furnace are also different.
