摘要: Abstract The microstructure design strategy of laminated structure was applied to improve the mechanical properties metal matrix composites (MMCs). were prepared by hot pressing and rolling alternately stacked Ti foils SiCp/Al composite foils, exhibited a superior strength-ductility synergy compared bulk MMCs. Coupling X-ray tomography digital image correlation (DIC) revealed that enhanced originated from contribution interface on local stress/strain transfer behaviors, thus delaying crack initiation propagation within layers.
