Special Issue Information

Dear Colleagues,

Composite materials can combine selected aspects of different materials to obtain beneficial properties. The properties of laminated composites depend on their structural design, component metals, performance matching, composite technology, interface morphology and microstructure, etc.

The advanced design theory, numerical simulation technology, and strengthening and toughening mechanism of laminated composites can effectively promote the performance improvement and application of laminated materials. Many studies have focused on the design of interface structures, gradient structures, homogeneous and heterogeneous metal composites, preparation processes, and mechanical properties of metal/non-metal, double, and multilayer multi-metal laminated composites.

This study investigates how Zr doping influences the deformation behavior of Cu-Zr/Al2Cu/Al composites through molecular dynamics simulations. The impact of Zr content (ranging from 0 to 0.8 wt%) and strain rate on phase evolution, dislocation dynamics, and fracture mechanisms under vertical and horizontal tensile loading was examined. The results indicate that Zr doping achieves a balance between strength and plasticity by means of solute drag, amorphization, and phase competition. At a Zr concentration of 0.2 wt%, the formation of the body-centered cubic (BCC) phase reached a peak (22.04% at ε = 0.11), resulting in a maximum tensile strength of 9.369 GPa while maintaining plasticity due to limited face-centered cubic (FCC) decomposition. A moderate Zr content of 0.6 wt% maximizes strength through amorphization but significantly diminishes plasticity due to excessive FCC-to-BCC transitions. Higher Zr concentrations (0.8 wt%) lead to solute supersaturation, which suppresses phase transitions and slightly reduces toughness by causing hexagonal close-packed (HCP) phase accumulation. The strain rate markedly enhances both strength and plasticity in vertical loading by accelerating dislocation interactions. Vertical tensile deformation initiates brittle fracture, whereas horizontal loading results in ductile failure through sequential load transfer from Al2Cu layers to Al/Cu interfaces, ultimately causing interfacial decohesion. These findings underscore the essential roles of Zr content and strain rate in modulating phase transformations and interface responses. The research offers a framework for creating gradient Zr-doped or multi-scale composites with optimized strength, plasticity, and damage tolerance suitable for aerospace and electronics applications, where trace Zr additions can reinforce Cu matrices.
