Special Issue Information

Dear Colleagues,

This Special Issue focuses on the latest research into aluminum alloys and their heat treatment, including new findings regarding the preparation, processing, and metallurgical quality control of aluminum alloys under different technical routes and external fields, as well as the correlation between heat treatment processes and material microstructure/mechanical properties.

The key areas of focus are high-quality aluminum alloy material preparation technology, the development of preparation equipment and processes for aluminum alloys, optimizing smelting and casting quality under external fields, microstructure-property regulation mechanisms, and sustainable heat treatment application strategies.

The current Special Issue aims to explore advanced technologies for aluminum alloy preparation and heat treatment, investigating the basic principles of metallurgical quality improvement and performance optimization. The articles presented in this Special Issue will address various topics, ranging from the development of new aluminum alloy systems to innovations in heat treatment processes and the industrial application of high-performance aluminum alloys.

Aluminum alloys are among the most widely used non-ferrous structural materials in industry, but their insufficient heat resistance severely restricts their application expansion in high-end scenarios, particularly in the aerospace field. As a crucial branch of next-generation heat-resistant aluminum alloys, the Al-Ce series alloys rely on the optimized design of alloying elements to enhance their heat resistance and comprehensive mechanical properties. Based on first-principles calculations using density functional theory (DFT), this study systematically investigated the effects of La and Nd single doping and co-doping on the crystal structure, elastic mechanical properties, lattice dynamics, thermodynamic properties, and electronic structure of the Al11Ce3 phase. The results demonstrate that all five doped phases exhibit dynamic and thermodynamic stabilities; among them, the Al11(Ce, La)3 phase shows the highest shear modulus (47.7 GPa), Vickers hardness (8.54 GPa), and Debye temperature (409 K). Furthermore, the synergistic doping of La and Nd can improve the metallicity and ductility of the alloy while maintaining high stiffness. Calculations on electronic properties further reveal the mixed bonding characteristics of Al-RE covalent bonds and metallic bonds, as well as their intrinsic correlation with mechanical property indicators. Our systematic study based on DFT calculations provides theoretical support for regulating the key strengthening phases of Al-Ce-based heat-resistant alloys through rare earth composite microalloying.
