The main GCP phase is γ'. Almost all superalloys are Ni-based because of this phase. γ' is an ordered L1 2 (pronounced L-one-two), which means it has a certain atom on the face of the unit cell, and a certain atom on the corners of the unit cell. Ni-based superalloys usually present Ni on the faces and Ti or Al on the corners.
Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts, wellhead parts, [44] and in the aerospace industry -- where it has become a prime candidate material for constructing heat resistant turbines.
The global lignite production is approximately one billion metric tons in 2012, with major production coming from Europe, the continent accounts for roughly 40% in lithium reserves. [23] The Kosovar lignite mines are operated at one of the most strategic lignite deposits in Europe, due to its geological conditions. [24]
For example, alloy 020 is designed to be resistant to sulfuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles. Incoloy 020 "exhibits excellent corrosion resistance in chemical environments that contain sulfuric acid, chlorides, phosphoric acid and nitric acid."

Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production. [1]

From left to right: three alloys (beryllium copper, Inconel, steel) and three pure metals (titanium, aluminum, magnesium)An alloy is a mixture of chemical elements of which in most cases at least one is a metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described.
