A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. The typical composition of a superalloy includes chromium, nickel, cobalt, molybdenum, tungsten, titanium, zirconium, hafnium, and niobium.
Some of the emerging trends in Superalloy include the development of new alloys with improved high-temperature strength and oxidation resistance, the use of 3D printing to create complex shapes, and the use of nanomaterials to improve mechanical properties.
