Abstract: The effects of laser power density on the mechanical properties of the LY12CZ aluminum alloy(including surface hardness and fatigue strength) were described. The results showed that with the increase of the laser power density, the materials hardness and fatigue strength increased. By microscopic analysis, the microstructures of the shocked and unshocked materials were compared. In addition, the building up of the shocked wave was studied and explored.
