Abstract

The paper concerns the surface modifications induced by high energy U.V. laser pulses on metals and alloys. SEM observations were carried out to evidence the surface morphologies after irradiation. Microhardness measurements showed that it is possible to increase the surface hardness of pure iron, Ti and Ti6Al4V alloy by formation "in situ" of finely dispersed precipitates. Residual stresses measurements were also carried out by X-ray diffraction technique to evidence the tensile state of the surface after laser irradiation.
