Ti–Al intermetallic alloys have a number of advantages for the manufacture of aviation and
car details. The use of these alloys is limited by their oxidation at high temperatures, which is …

Analytic expressions for the temperature-dependent diffusion coefficient of oxygen along two
directions in the α 2-Ti 3 Al alloy are obtained using Landman's method. The estimation of …

Titanium alloys are attractive to the industrial world, as they offer the benefits of low density,
great corrosion resistance, and relatively good strength, making them viable candidates for a …

Air oxidation behaviour of a Ti–6Al–4V alloy was examined over the temperature range of
600–800° C for different time intervals ranging between 0.5 and 72h. In addition to the …

This paper presents research results on the oxidation of γ-TiAl-based alloys collected over
many years. The oxidation exposures were carried out in air at 875–975° C. Micro-areas …

The projector augmented-wave method within the density functional theory is applied to
investigate the oxygen diffusion in the intermetallic Ti-Al alloys. It is shown that the highest …

Method of the projector augmented waves in the plane-wave basis within the generalized-
gradient approximation for the exchange-correlation functional has been used to study …

It is known that the oxide scale formed on TiAl alloys is generally composed of a mixture of
alumina (Al2O3) and titania (TiO2). The presence of niobium changes the activities of Ti and …

The oxidation kinetics of TiAl alloys with and without 3 and 5 wt.% additions of Si 3 N 4
particles were studied at 1173 and1273 K in 1 atm of air. The Si 3 N 4 dispersions …

The characterization of oxygen diffusion zone in titanium and the effect of this zone on
macroscopic properties are still of high interest for a base to predict and to enhance life time …
