    Abstract. The thermodynamics of the Ni-Al-B system are assessed based on available literature data. Both the Ni-B and Al-B systems were revised to treat B as an interstitial element in a face-centered cubic structure, rather than as a substitutional by:   The phase diagram of the Al-Cu binary system was reinvestigated experimentally. The current study was designed to contribute to a better description of those parts of the phase diagram which are disputed in the current scientific literature, and in addition, to study the phase equilibria at °C. The melting behavior of the θ-phase was confirmed to Cited by: 5.

    Intermetallic phases exhibit a vast structural diversity in which electron count is known to be one controlling factor. However, chemical bonding theory has yet to establish how electron counts and structure are interrelated for the majority of these compounds. Recently, a simple bonding picture for transition metal (T)–main group (E) intermetallics has begun to take shape based on Cited by: Schulze in defined intermetallic compounds as solid phases containing two or more metallic elements, with optionally one or more non-metallic elements, whose crystal structure differs from that of the other constituents. Under this definition, the following are included: Electron (or Hume-Rothery) compounds.

The geometric structures of intermetallic phases are determined by a complex interplay of various bonding types. Ionic and covalent interactions caused by charge transfer among the atoms and by local electronic structures compete with the forces that itinerant electrons exert on the atomic cores.

Formation of the complex structure with 16 atoms in the orthorhombic cell, space group Cmca (Pearson symbol oC16), was experimentally found under high pressure in the alkali elements (K, Rb, Cs) and polyvalent elements of groups IV (Si, Ge) and V (Bi).

Intermetallic phases with this structure form under pressure in binary Bi-based alloys (Bi-Sn, Bi-In, Bi-Pb).Cited by: 8. Creep of the orthorhombic phase based on the intermetallic Ti 2AlNb.

The orthorhombic phase based on Ti2AlNb intermetallic is an important constituent of several alloys currently under investigation as both monolithic products and as matrix material for intermetallic–matrix composites. The main focus of this book is on the statistics, topology and geometry of crystal structures and structure types of intermetallic phases.

The underlying physics, in particular chemical bonding, is discussed whenever it helps understand the stability of structures and the origin of their physical properties.

cent, as shown in Figure 5. Single-phase alloys follow the lines drawn while two-phase alloys have considerable scatter. RuTa, like the other L1, crystal type IrNb, has a fine structure of twins (Figure 6) or alter- nating lamellar phases (in this case L1, and B2) (7).

As Figure 7 shows, the layer structure ap- pears clearly on fracture surfaces. orthorhombic crystal system Crystals in an orthorhombic system are characterized by three mutually perpendicular axes that are unequal in length.

In the orthorhombic system there is a rarely used second choice of crystal axes that results in a unit cell with the shape of a right rhombic prism; it can be constructed because the rectangular two-dimensional base layer can also be described with rhombic axes.

In this axis setting, the primitive and base-centered lattices swap in centering type, while the same thing happens.

The Cubic crystal system is also known as the "isometric" system.

The Cubic (Isometric) crystal system is characterized by its total symmetry. The Cubic system has three crystallographic axes that are all perpendicular to each other and equal in length.

TiSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ti4+ is bonded in a 7-coordinate geometry to seven equivalent Si4- atoms. There are a spread of Ti–Si bond distances ranging from – Å. Si4- is bonded in a 9-coordinate geometry to seven equivalent Ti4+ and two equivalent Si4- atoms.

In the absence of Nb, the alloy showed a single-phase FCC structure in the coating, while the Nb-containing coating showed a (CoCr)Nb-type Laves phase along with a FCC phase (Figure ). The Nb-containing coating showed significant improvement in hardness, Young’s modulus, wear resistance, and corrosion resistance in comparison to the coating without Nb.
