Dual Role of Nb in Defect-Mediated Strength and Ductility of γ-TiAl Alloys
Zhiqiang Zhao, Siyao Shuang, Kepeng Ouyang +8
The origin of the superior high-temperature strength of γ-TiAl with high Nb addition remains highly controversial, largely due to the unclear role of Nb atoms. Using large-scale h…
