The formation of intermetallic compounds at the interface would stabilize the microstructure to avoid the degradation of its various properties during exposure to elevated temperatures, such as those encountered during emergency overload situations.
32.
An intermetallic compound can be defined as an ordered alloy phase formed between two metallic elements, where an alloy phase is ordered if two or more sublattices are required to describe its atomic structure.
33.
Although the term " intermetallic compounds ", as it applies to solid phases, has been in use for many years, its introduction was regretted, for example by Hume-Rothery in 1955.
34.
In these alloys'W'is the crucial addition for getting ? intermetallic compound that makes them much denser ( > 9.6 gm / cm 3 ) compared to Ni-based superalloys.
35.
And multicomponent intermetallic compounds, quasicrystals, oxides, ceramics, nanostructural controlled metals, semiconductors, crystals for solar cells, biomaterials, organic materials, hydrogen storage alloys, and shaped crystals, etc.
36.
Transition metals and intermetallic compounds based on transition metals can exhibit mixed metallic and covalent bonding, resulting in high shear strength, low ductility, and elevated melting points; a classic example is tungsten.
37.
In the resonating valence bond theory, the factors that determine the choice of one from among alternative crystal structures of a metal or intermetallic compound revolve around the energy of resonance of bonds among interatomic positions.
38.
After the war he returned to Oxford " " to carry on research in intermetallic compounds and problems on the borderland of metallography and chemistry " " and remained there for the rest of his working life.
39.
In an ordinary alloy, the constituents are randomly positioned on the crystal lattice; in an ordered intermetallic compound, the atoms ( in this case, nickel and titanium ) have very specific locations in the lattice.
40.
The most common oxidation states for arsenic are : " 3 in the arsenides, which are alloy-like intermetallic compounds, + 3 in the arsenites, and + 5 in the arsenates and most organoarsenic compounds.
