Abstract γ-TiAl alloys, as the high temperature and lightweight structural material, have been
applied in aerospace and automotive industry, and will remain the focus of research …

After almost three decades of intensive fundamental research and development activities,
intermetallic titanium aluminides based on the ordered γ‐TiAl phase have found …

To improve the strength and ductility of TiAl alloys by second phase, Ti46Al4Nb1Mo alloys
doped with different B content (0.4%, 0.8%, 1.2%, 1.6% and 2.0%, atomic percent, hereafter …

The influence of the Al content and the addition of further alloying elements on the cast
microstructure of γ (TiAl)+ α2 (Ti3Al) alloys has been examined. The results show that …

The thermodynamic description of the entire ternary Al–Nb–Ti system is obtained by
CALPHAD modelling of the Gibbs energy of all individual phases, taking into account …

In recent years, additive manufacturing of titanium aluminide has become an attractive
research area. In order to improve microstructure and mechanical properties, element …

This work presents a comprehensive study on the laser scanning speed on the
microstructure development, phase evolution and nanohardness of a TiAl alloy, Ti-45Al-2Cr …

Strengthening of TiAl-based intermetallic alloy is vital for its broader application, however,
microstructural refinement through conventional processes is difficult to further strengthen …

The lamellar microstructure of TiAl–Nb alloys with and without low boron additions is
controlled using double directional solidification (DS). In alloys without the addition of boron …

In order to improve mechanical properties, different Ta contents were added into
Ti42Al6Nb2. 6C alloys, which were prepared by vacuum arc melting. Microstructure …
