Abstract

Residual microstructures associated with hypervelocity impact craters in 55vol.% TiB ₂/2024Al composite were investigated by transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). TiB ₂-Al interface, TiB ₂ particles and Al matrix before and after hypervelocity impact were compared to discuss the effect of hypervelocity impact. A new Al _xO _1-x phase with the fcc structure and the crystal parameter of 0.69nm was formed at TiB ₂-Al interface. Stacking fault with width of 10-20nm was formed along the (001) plane of TiB ₂ particle. Formation of nanograins (~100nm) was observed within Al matrix, moreover, lamellar S' phase was transformed into lenticular or spherical S phase after hypervelocity impact.
