Plasticity of γ-TiAl alloys
… well as in high performance automobiles and potentially the nuclear industry. The lack of toughness of its two constitutive intermetallic phases, γ-TiAl and α2-Ti3Al, prevents a conventional damage tolerant approach to fatigue lifing. To gain confidence in the use of γ-TiAl alloys and extend the …

Mechanisms of Deformation and Fracture in TiAl: An Atomistic Simulation Study
The intermetallic compound TiAl possesses a unique complex of properties that include sufficiently low material density, high values of the strength-to-ductility ratio, high elastic moduli, high oxidation resistance, low creep rate, and improved fatigue characteristics. These properties make TiAl …

Defect Structures in Ordered Intermetallics; Grain Boundaries and Surfaces in FeAl, NiAl, CoAl and TiAl
… aluminides, FeAl, NiAl and CoAl and <I>L</I>1₀ γ-TiAl were investigated using molecular statics and embedded atom potentials in order to explore general trends for a series of B2 compounds as well as TiAl. The potentials used correctly predict the proper mechanism of compositional disorder of …

Formation And Growth Mechanisms of a High Temperature Interfacial Layer Between Al and TiO2
… analytical techniques; and the formation of TiAl as the interfacial compound is described. The thermodynamics of the Al – Ti – O system is explained as it relates to the particular conditions for the Al – TiO2 reaction research. Thermodynamic principles have been used to demonstrate that the …

The machinability of a gamma titanium aluminide intermetallic
… of the gamma titanium aluminide intermetallic (-TiAl) Ti-45Al-8Nb-0.2C currently under evaluation to be the material of choice for blades and stators in the intermediate compressor (IP) and low pressure (LP) turbine sections of an aeroengine due to the alloys high temperature (~800C) and low …

The effect of nitrogen, niobium and temperature of the high temperature oxidation of titanium aluminide alloys
… set of three intermetallics -- unalloyed [gamma]-TiAl, unalloyed [alpha]-Ti 3Al and a nearly stoichiometric Ti2NbAl (an orthorhombic intermetallic structure) -- was chosen and investigated under a variety of experimental conditions. Gas mixtures of varying oxygen concentrations in both argon and …

Numerical modelling of the tilt casting processes of titanium alumindes
… the tilt casting process of Titanium Aluminides (TiAl). This study is carried out in parallel with the experimental research undertaken in IRC at the University of Birmingham. They propose to use tilt casting inside a vacuum chamber and attempt to combine this tilt casting process with Induction …

Deformation processed IMC-reinforced metal matrix composites
… of utilizing TiB₂-reinforced near-gamma TiAl intermetallic matrix composites (IMCs) as a reinforcing entity within a commercially pure Ti matrix was investigated. IMCs are "ceramic-like" at ambient to moderate temperatures, and “metallic-like" in their deformation behavior above their …
