Microstructure characterization of Al matrix composite reinforced with Ti-6Al-4V meshes after compression by scanning electron microscope and transmission electron microscope

► The strain-rate sensitivity (R) of composite increased with the increasing temperature. ► TC4 fibres were sheared into several parts at the strain rate of 10−3 S−1. ► Cracks were produced at the interface between TC4-Al at a strain rate of 10−3 S−1. ► Interfacial separation of TC4-Al occurred at the strain rate of 1 S−1. ► Dislocations transmitted to equiaxed recrystals in Al as temperature increases.
