TiAl-based alloy is an excellent high-temperature structural material, but poor hot workability
has been the bottleneck hindering its development. In this study, we take into account the …

In most metallic materials, the strength-ductility trade-off serves as an inevitable scenario.
Therefore, improving the room/high-temperature strength/ductility of high Nb-TiAl alloys …

The effect of niobium on microstructure and mechanical properties of Ti46Al2. 6C xNb (at.%)
alloys with Nb content ranging from 0 to 8 at.% have been studied. The alloys have been …

A preferentially-aligned lamellar structure in TNM alloy with enhanced strength-ductility
synergy is successfully obtained by texturing the high-temperature α phase through hot …

TiAl alloys are ideal high-temperature structural materials for aerospace applications.
However, their ductility, bending strength and machinability are poor at room temperature …

This study aims to investigate the influence of high-temperature heat treatment on the
microstructure and mechanical properties of titanium aluminide niobium (γ-TiAlNb) …

Understanding the non-equilibrium phase transition mechanism is critical to controlling the
transforming microstructures and thus material performance. In order to improve the problem …

In this paper, the deformation and phase transformation of disordered α phase in the (α+ γ)
two-phase region in as-forged Ti-44Al-8Nb-(W, B, Y) alloy were investigated by hot …
