| Abstract Scope |
The ordered arrangement of atoms plays a pivotal role in governing the strength and ductility of structural metallic materials. However, how to effectively manipulate the atomic order to overcome the longstanding strength-ductility trade-off remains a challenge. Atomic manufacturing, a revolutionary approach to create entirely novel materials with disruptive capabilities, exhibits immense promise to overcome this challenge. Herein, we introduce pulsed laser deposition to fabricate diverse nanostructures with varying degrees of order in a typical Zr50Cu40Al10 alloy composition. These structures demonstrate a broader range and superior mechanical properties compared to existing Zr-based alloys. Notably, a balance between strength and ductility has been achieved in both spinodal glass and dual-phase nanostructures. The novel spinodal glass exhibits an ultrahigh yield strength of 3.89 GPa combined with over 70% strain of compression. This work highlights the tremendous potential of atomic manufacturing and structural order modulation in exploring materials with versatile and optimal performances. |
