Aiming at tailoring the tensile properties of the heterostructured alloy, a method was proposed to modulate the RX fraction by annealing. The as-extruded sample exhibited a high yield strength (YS) of 371 MPa, but its elongation (EL) was only 7.5%. After annealing at 250 掳C, an optimal ...

However, increasing strength usually comes at the expense of ductility, which is known as strength-ductility trade-off. In this work, we explored a novel interface design strategy by introducing multi-scale grains into the bonding interface of the Ti2AlNb-based alloy using a heterogeneous ...
Many strategies have been proposed to tailor structural heterogeneities to promote the strength-ductility synergy in HEAs8. Generally, these strategies are associated with the manipulation of grain-size heterogeneity, precipitation, dual-phase microstructures, interstitial complex, and short-range ordering (...

In this study, lightweight and non-equiatomic MEAs with low density (~5 g/cm3), high strength (yield strength: 1200 MPa), and high ductility (plastic deformation: ≧10%) were explored. We fine-tuned a previously developed Ti-rich MEA by microalloying it with small amounts of...
Nanoparticle reinforced aluminum matrix composites fabricated by a high energy ball milling method showed significantly improved strength, however, their ductility was relative lower. This study proposed for the first time a heterogeneous structure strategy toward good strength and ductility synergy for Al ...
