Abstract Al-Sc and Al-Ti semi-infinite targets were impacted by stainless steel projectiles with velocity range of 0.6–1.9 km/s. It was found that the Al-Sc targets demonstrated a much better ability to resist hypervelocity impact. It is concluded that different microstructures of Al-Sc and Al-Ti alloys, including different grain sizes and secondary particles precipitated in the matrix, result in their greatly different abilities to resist impact. Furthermore, the effect of the size range of nanoscale Al3Sc precipitates in Al-Sc target on the resistance of hypervelocity impact was investigated. Simultaneously, the response of Al3Sc precipitates on shock wave propagation generated by hypervelocity impact was analyzed.
