Special Issue Information

Dear Colleagues,

This Special Issue focuses on recent progress in advanced alloys for engineering structures, emphasizing design methodologies and performance improvements. As the demand for higher efficiency and durability in engineering applications grows, advanced alloys play a crucial role. The contributions in this issue showcase innovative alloy compositions, novel processing techniques and advanced characterization methods that enhance material properties.

Key topics may include (but need not be limited to) integrating computational materials science in alloy design to tailor properties for specific applications and utilizing techniques like additive manufacturing for optimum performance. Additionally, the issue reviews performance metrics under various environmental conditions, providing insights into the long-term behavior of these materials in real-world scenarios.

The research highlights contributions to structural integrity while addressing sustainability, promoting eco-efficient practices in material selection and application. By compiling diverse studies, this Special Issue aims to serve as a vital resource for researchers and engineers looking to innovate in advanced alloys, ultimately driving progress in engineering structure design and performance.

We look forward to receiving your contributions.

Four interfacial configurations were constructed via molecular dynamics simulations: an interface-free model, a single Mg2Al3 layer, a single Mg17Al12 layer, and a Mg17Al12/Mg2Al3 composite bilayer. This study aimed to clarify how interfacial phase compositions govern the tensile properties and failure mechanisms of Al/Mg layered composites under in-plane interfacial tension. The results show that the Mg17Al12 monolayer model exhibits the best performance, with a tensile strength of 1.702 GPa, representing a 31% improvement compared to the model without an interfacial layer. The composite bilayer model yields a 14% improvement, whereas the Mg2Al3 monolayer model shows a slight decrease in strength. Failure analysis revealed crack initiation at the matrix grain boundaries in the interface-free and Mg2Al3 monolayer models, but within the interfacial region in the Mg17Al12 monolayer and composite bilayer models. This study reveals the differences in the deformation mechanisms between composite and single interfacial layers, providing a theoretical reference for interface optimization design. Full article
