It develops high-throughput preparation technologies and devices for rapid screening of high-stiffness magnesium alloy compositions and reinforcements, achieving co-furnace and synchronous preparation of large-capacity sample groups (≥150 samples). Furthermore, this project establishes the relationship among composite compositions, preparation processes, structured microstructures and macroscopic mechanical properties, conducts inverse optimization of material systems and their preparation processes, and develops ultra-high stiffness magnesium matrix composites with excellent comprehensive properties. Based on in-situ characterization technologies including optical microscopy, scanning electron microscopy (SEM) and three-dimensional X-ray microscopy, combined with digital image correlation (DIC) algorithm, it carries out in-situ studies on the influence mechanism of reinforcement composite structured microstructures on local strain evolution and fracture behavior, thereby elucidating the strengthening and toughening mechanisms of the composites.
