  2. Nickel titanium - Wikipedia

    en.wikipedia.org/wiki/Nickel_titanium

    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.

  3. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    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.

    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 ...

  5. Superalloy - Wikipedia

    en.wikipedia.org/wiki/Superalloy

    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 ...

    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 ...

  8. Metallocene - Wikipedia

    en.wikipedia.org/wiki/Metallocene

    General chemical structure of a metallocene compound, where M is a metal cation. A metallocene is a compound typically consisting of two cyclopentadienyl anions (C 5 H − 5, abbreviated Cp) bound to a metal center (M) in the oxidation state II, with the resulting general formula (C 5 H 5) 2 M. Closely related to the metallocenes are the metallocene derivatives, e.g. titanocene dichloride or ...

  9. Silicide - Wikipedia

    en.wikipedia.org/wiki/Silicide

    Most silicides are produced by direct combination of the elements. [1]A silicide prepared by a self-aligned process is called a salicide.This is a process in which silicide contacts are formed only in those areas in which deposited metal (which after annealing becomes a metal component of the silicide) is in direct contact with silicon, hence, the process is self-aligned.
