This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Within these headings, the alloys are also grouped alphabetically.
Nickel-based superalloys are used in load-bearing structures requiring the highest homologous temperature of any common alloy system (Tm = 0.9, or 90% of their melting point). Among the most demanding applications for a structural material are those in the hot sections of turbine engines (e.g. turbine blade). They comprise over 50% of the ...
Coins still made with nickel alloys include one- and two-euro coins, 5¢, 10¢, 25¢, 50¢, and $1 U.S. coins, [73] and 20p, 50p, £1, and £2 UK coins. From 2012 on the nickel-alloy used for 5p and 10p UK coins was replaced with nickel-plated steel. This ignited a public controversy regarding the problems of people with nickel allergy. [68]
Alloys primarily of nickel and chromium. These are usually chosen for their behaviour at high temperatures, either resistance to chemical and physical erosion, or to mechanical creep . Pages in category "Nickel–chromium alloys"
Monel is a group of alloys of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Monel is not a cupronickel alloy because it has less than 60% copper. Stronger than pure nickel, Monel alloys are resistant to corrosion by many aggressive agents, including rapidly flowing seawater. They can be ...
For γ’ volume fractions of 0.4 to 0.6 in nickel-based alloys, the threshold stress for local climb is only about 1.25 to 1.40 times higher than general climb. [8] Dislocations are not limited to either all local or all general climb as the path that requires less energy is taken.
In steel metallurgy, nickel is alloyed with iron since 1888 (date of Schneider et Cie's patent [5] on nickel steel based on Jean Werth's research [6]) to produce maraging steel and some low-alloy steels. Other technological uses include Invar and Mu-metal.
