    Abstract
  • The attenuation of planar shock waves in LY12-M aluminum was measured with the manganin piezoresistive gages. The peak pressure of shock waves initially is 4.92 GPa. Both the positron lifetimes and the vickers microhardness were measured. The influences of dislocations and other crystal defects on the nonhydrodynamic attenuation of shock waves as well as the shock hardening effect in LY12-M aluminum are discussed.
