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.
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons; Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion; Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira; Magnalium (5-50% magnesium): used in airplane bodies, ladders, pyrotechnics ...
It is also used to construct valves for molten zinc. [11] Molybdenum is used in mercury wetted reed relays, because molybdenum does not form amalgams and is therefore resistant to corrosion by liquid mercury. [12] [13] Molybdenum is the most commonly used of the refractory metals. Its most important use is as a strengthening alloy of steel.
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.
The most common materials for vacuum casting process are the high nickel-based alloy and super alloys. Turbocharger products are a common applications for this casting process, [ 22 ] though it is also regularly used in the manufacture of silver and gold jewellery.

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]
