Special Issue Information

Dear Colleagues,

The increasing demand for high performance in the aerospace, automotive, electronics, and energy industries has pushed researchers into exploring novel solutions. Metal matrix composites can achieve great mechanical, thermal, and functional properties, thereby suiting advanced engineering applications. In-depth research on metal-based composite materials assists in breaking through technical bottlenecks in both material design and preparation, thus promoting innovative development in material science.

We are pleased to announce this Special Issue, entitled “Processing and Characteristics of Metal Matrix Composites”. This collection aims to collect state-of-the-art research articles and comprehensive review papers in the field of metal matrix composites. This Special Issue welcomes the submission of high-quality research in this field, focusing on material design, microstructural characteristics, performance characterization, multi-scale microstructure modelling, processing techniques, and innovative application in engineering.  

All articles published in this Special Issue are subject to careful editorial selection. We intend for this Special Issue to provide a forum for disseminating excellent research findings and sharing innovative ideas in the field.

The present study concentrates on the role and underlying mechanisms of in situ crystallization (employed for nanocrystal formation) in influencing the solidification microstructure and properties of aluminum alloys. By systematically analyzing the effects on α-Al refinement, silicon phase modification, and secondary phase control, as well as exploring the impact on room-temperature mechanical properties, high-temperature deformation behavior, and fatigue performance, this work reveals the potential physical mechanisms of improving mechanical properties by providing nucleation sites and inhibiting grain growth, such as fine-grain strengthening and dispersion strengthening. Moreover, stabilization of the second phase optimizes high-temperature deformation behavior, and a reduction in stress concentration improves fatigue performance. Compared with traditional microstructure control methods, in situ crystallization can achieve deeper grain refinement from micron to nanometer scale, ensuring high uniformity of grain distribution and showing good compatibility with existing processes. By defining the regulation of in situ crystallization on the microstructure and properties of aluminum alloy, the existing research provides a feasible material solution for high stress, high temperature, and high reliability. Its core significance lies in breaking through the performance bottlenecks of traditional modification technology, such as unstable refining effect, element segregation, and so on. The co-promotion of “strength–plasticity–stability” of aluminum alloys and the consideration of process compatibility and cost controllability lay a theoretical and technical foundation for the industrialization of high-performance aluminum alloys.
