“…The enhancement of strength up to 2 GPa in UECs has occurred due to the presence of hard intermetallic nano-lamellar phase(s) in the matrix of Ti-Cu-Ni-Sn-Nb [22], Zr-Cu-Ni-Al-Nb [23], Ti-FeSn [13][14][15][16][17], Fe-Nb-(Al/Mn/Ni) [3,24], Al-Cu-Si [25], and Ni-Zr [4,26,27]. Whereas, the improvement of compressive plasticity of UECs have been interlinked with the formation of large number of shear bands [28,29], and localized rotation of the colony boundaries to effectively dissipate the shear stress [10,11,[20][21][22]25], which have been further assisted due to the change in the lamellar morphology upon alloy additions [21].…”
