High-Nb TiAl-Based Composite

6× room-temp plasticity

A fine lamellar microstructure with synergistic distribution of Si atoms and TiB/Ti5Si3 precipitates simultaneously enhances strength and ductility at room and elevated temperatures, overcoming the strength-ductility dilemma in conventional TiAl alloys.
