Paper Abstract

Pulsed lasers are being used to generate high amplitude stress waves in metals and change their mechanical properties. Peak pressures greater than 5 GPa are generated in a metal or alloy when it is covered with a transparent material. These pressures exceed the Hugoniot elastic limit of most metals and produce networks of tangled dislocations in the metals substructure which is the source of the observed change in material properties. The strength, hardness, and fatigue properties of 7000 series aluminum alloys are improved in this manner. Weld zones in aluminum are strengthened up to the bulk level and the surface hardness of stainless steel is increased.
