Abstract
In this study, AZ31/6013 composite sheets were produced via hot roll bonding and annealed to investigate microstructural evolution and mechanical properties at the interface. Using scanning electron microscopy, energy-dispersive X-ray spectroscopy, electron backscatter diffraction, and transmission electron microscopy, interface microstructures were analyzed. Annealing at 400°C for 2 h resulted in the formation of two diffusion layers, each approximately 100 μm thick. The intermetallic compounds Al3Mg2 and Mg17Al12 exhibited elastic moduli of 68.649 GPa and 74.857 GPa, respectively, with Al3Mg2 demonstrating a higher average hardness (4.353 GPa compared to 4.157 GPa for Mg17Al12). Subsequent annealing at 200°C for 4 h led to improved tensile properties, achieving a peak strength of 176.7 MPa and an elongation of 19.1%.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
