It is now well known that the room temperature tensile yield strength (σy), fracture strength
(σf), and ductility (δ) of TiAl alloys increase with decreasing the colony size (d) of the fully …

It is of significance, but still remains a key challenge to overcome the strength–ductility trade-
off, and homogenize the mechanical performance of the additively manufactured titanium …

The graphene network (GN) reinforced Ti6Al4V composites with concurrently enhanced
strength and ductility are fabricated based on powder metallurgy, in which the GN interlocks …

A pre-deformation process was employed for a TiAl alloy via high-temperature torsion, in
which the stability of the constituent phases was tailored, resulting in enhanced hardening …

The strength-ductility trade-off is a long-standing challenge in engineering and material
sciences. The introductions of twin boundary or phase boundary in materials have been …

The aim of this study is to determine the influence of lamellar orientation on the strength and
operative deformation mechanisms of a fully lamellar Ti-45Al-2Nb-2Mn (at.%)+ 0.8 (vol.%) …

The distribution of strain in hard mode oriented lamellar stacks of the two-phase γ-TiAl/α 2-Ti
3 Al alloy Ti-45Al-2Nb-2Mn (at.%)-0.8 vol% TiB 2 was measured at several temperatures up …

Nanostructured intermetallics generally exhibit high strength but limited plasticity due to the
covalent nature of their bonding. In this study, high-pressure torsion followed by annealing …

TiAl matrix composites, reinforced with varying Ti 2 AlC content levels, were synthesized by
vacuum arc melting by use of Ti, Al and graphite powders as raw materials. The effects of …

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