Compounds of nickel with other metals can be called alloys. The substances with fixed composition include nickel aluminide (NiAl) melting at 1638° with hexagonal structure. [4] NiY, NiY 3, Ni 3 Y, Ni 4 Y, NiGd 3, [16] BaNi 2 Ge 2 changes structure from orthorhombic to tetragonal around 480 °C. [17] This is a ternary intermetallic compound.
Nickel was not formally named as an element until A. F. Cronstedt isolated the impure metal from "kupfernickel" (Old Nick's copper) in 1751. [11] In 1804, J. B. Richter determined the physical properties of nickel using a purer sample, describing the metal as ductile and strong with a high melting point.
The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be Cs > K > Na > Li > alkaline earth metals, i.e., alkali metals > alkaline earth metals, the same as the reverse order of the (gas-phase) ionization energies.
In chemistry, the acronym NiFe refers to an iron–nickel catalyst or component involved in various chemical reactions, or the reactions themselves; in geology, it refers to the main constituents of telluric planetary cores (including Earth's). Some manufactured alloys of iron–nickel are called nickel steel or stainless steel.
Magnesium is a minor additive in many aluminum coins; this alloy is called magnalium. Nickel: Used unknowingly in alloys since antiquity. The first pure nickel coin was the Swiss 20 Rappen of 1881. A book published by the International Nickel Company of Canada in 1933 lists dozens of coins minted out of nickel. Phosphorus
In order to improve the oxidation resistance of these alloys, Al, Cr, B, and Y are added. The Al and Cr form oxide layers that passivate the surface and protect the superalloy from further oxidation while B and Y are used to improve the adhesion of this oxide scale to the substrate. [ 4 ]
