Residual microstructure associated with impact crater in Ti-6Al-4V meshes reinforced 5A06Al alloy matrix composite

► Near the pithead, TC4 fibers and Al matrix separated along the impact direction. ► Around the middle of the crater, TC4 fibers were sheared into several sections. ► Near the bottom of crater, ASB occurred in TC4 fiber. ► The crack propagated along TC4-Ti3Al interface during impact. ► Ti3Al phase at the TC4-Al interface transformed to amorphous after impact.
