Nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages.Different alloys are named according to the weight percentage of nickel; e.g., nitinol 55 and nitinol 60.
[9] [10] However, not all sources give the same values: there are some differences between the precise values given by NIST and the CRC Handbook of Chemistry and Physics. In the first six periods this does not make a difference to the relative order, but in the seventh period it does, so the seventh-period elements have been excluded.
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.
Examples include: [5] Ti-6Al-4V, Ti-6Al-4V-ELI, Ti-6Al-6V-2Sn, Ti-6Al-7Nb, and Ti62A [6] Beta and near beta alloys, which are metastable and which contain sufficient beta stabilisers (such as molybdenum, silicon and vanadium) to allow them to maintain the beta phase when quenched , and which can also be solution treated and aged to improve ...
Ti 3 O 5, described as a Ti(IV)-Ti(III) species, is a purple semiconductor produced by reduction of TiO 2 with hydrogen at high temperatures, [41] and is used industrially when surfaces need to be vapor-coated with titanium dioxide: it evaporates as pure TiO, whereas TiO 2 evaporates as a mixture of oxides and deposits coatings with variable ...
For example, Ti (Z = 22) is in period 4 so that n = 4, the first 18 electrons have the same configuration of Ar at the end of period 3, and the overall configuration is [Ar]3d 2 4s 2. The period 6 and 7 transition metals also add core ( n − 2)f 14 electrons, which are omitted from the tables below.
Ni 2 Fe to Ni 3 Fe Earth's core: Earth's core is composed of an iron–nickel alloy [8] about 5.5% Ni: Elinvar: A manufactured alloy whose elasticity does not change with temperature; 5% Cr: 36% Ni: Invar: A steel manufactured to have a very low thermal expansion: 36% Ni: Kamacite: A native metal found in meteoric iron: Fe [0.9] Ni [0.1 ...
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]
