| Abstract | Overcoming the strength-ductility trade-off in metals and alloys entails the optimization of the compositions and dedicated microstructural design, which remains experimentally laborious and challenging. Here, a combinatorial method is devised to construct a Cu-Ti alloy library encompassing diverse compositions, microstructures, and mechanical properties, allowing to efficiently identify a copper alloy with an unprecedented yield strength of 3.8 GPa and high deformability. The exceptional properties are attributed to a crystal-glass nano-heterostructure (CGNH) consisting of nanograins, nano twins, and glassy phases. Ultrahigh strength stems from the extreme strengthening of structural-unit refinement and the avoidance of softening caused by grain-boundary sliding through the inclusion of glassy phases between nanograins. Remarkable deformability is associated with the activation of homogeneous flow in nanosized glassy phases, complemented by coordinated nanocrystal rotation. The CGNH architecture offers a potent route to overcome the trade-off between alloy strength and deformability. A modular combinatorial method is developed to create a Cu-Ti alloy library with diverse microstructures and properties. This allows for the efficient identification of a crystal-glass nano-heterostructure (CGNH) comprising nanograins, nanotwins, and glassy phases, achieving exceptional mechanical properties. The CGNH overcomes the alloy strength-deformability trade-off through extreme refinement strengthening, activation of homogeneous flow in glassy phases, and avoidance of grain-boundary sliding. image |
