Dimensional crystal geometry of binary intermetallic alloys

“…Earlier, we have shown that alloys of a А 3 В composition with the hexagonal structures (here belongs the D0 24 structure, Fig. 3c) occupy a significant range of the scaling factor values: from 0.8 to 1.4 [15]. The numerical scaling factor values of the intermetallic Ni 3 Ti compound with the D0 24 structure fall practically in the very center of the interval of possible values, which is given in the distribution in Fig.…”

The work deals with a search for general crystallogeometrical regularities in binary alloys in a Ni-Ti system. The histograms of the В2, В19, D0 24 and E9 3 structure distributions are constructed in binary systems as a function of the space filling coefficient and superstructure compression. It is shown that the packing density and phase formation enthalpy in the Ni-Ti system increase concurrently.

“…The best examples of D0 22 and D0 23 intermetallics are TiAl 3 and ZrAl 3 , respectively. [ 33 ] It is observed that, in general, all group V trialuminides produce D0 22 crystal structure whereas group III trialuminides create L1 2 crystal structure. [ 34 ] However, the group IV trialuminides are having metastable L1 2 structure and readily transforms into either D0 22 or D0 23 structures.…”

Advancement in modern manufacturing processes is allowing researchers to develop new alloy configurations for different applications to reduce weight and increase efficiency. Many alloy combinations are produced that randomly generate different phases of intermetallic compounds (IMCs) in the structure during manufacturing which show unique mechanical and chemical properties. But, the fundamental knowledge of different IMCs is scattered across the material research domain. Thus, in this review, the crystal structures of IMCs are thoroughly discussed which are having structural and functional applications. Furthermore, the issues associated with the dissimilar Fe‐Al, Fe‐Ni, and Ni‐Al systems via modern manufacturing processes such as arc additive manufacturing have been discussed. Moreover, detailed knowledge of ferro‐nickel, nickel‐aluminides, and ferro‐aluminides formed at the interface during the dissimilar deposition in modern manufacturing is provided. Currently, a few transition metal IMCs and some Heusler alloys, are the most promising and are used in applications. The addition of a third alloying element provides the broadening effect on the phase domain of a specific IMC. Furthermore, it has been observed that modern manufacturing processes such as additive manufacturing and others are new and advanced manufacturing technologies used for dissimilar metal deposition, which can control the IMCs in a more favorable direction.
