Effect of yttrium and erbium on the microstructure and mechanical properties of Ti–Al–Nb alloys

▶ Room plasticity and toughness of the alloy was enhanced greatly by adding Er element. ▶ Different characteristics of Y and Er leads to different alloy's properties. ▶ By structure reconstruction, a new (AlTiNb) 2Er 3 precipitated phase was identified. ▶ Ti–16Al–27Nb–0.6Er alloy undergoes SIMT...
