Influence of hetero-duplex structure on mechanical properties of Mg–Al/Cu–Zn alloys

Enhancement of mechanical properties in a Fe81Nb9B10 ultrafine-eutectic composite with in-situ polygonal pro-eutectic and encapsulating eutectic structure

“…However, their limited deformability and shear localization tendency at room temperature have been considered as a critical drawback for commercial application [3,4]. In order to overcome this disadvantage, new types of nanostructured composites containing dendritic second phase dispersions or ultrafine eutectic phases with structural heterogeneity, i.e., different length scale in lamellar spacing and eutectic colonies, have been developed in Ti-, Al-, Mg-, Ni-and Fe-based multicomponent alloys [5][6][7][8][9]. In particular, Ti-based dendrite-ultrafine composite exhibits a superior combination of both a high strength of 1.2 GPa and a plastic strain of more than 10% at room temperature [10].…”
