Paper Abstract

A nondestructive technique for the quantitative evaluation of defects in metal structures is described. The surface of the metal is irradiated by a short xenon lamp pulse and monitored by a thermal image processor. The analysis relates to the time decay signal of the front face temperature, which contains information on the thermophysical properties and subsurface defects of the material. The time history of the surface temperature is then used to quantify the substructure of the material. Applications for the inspection of aluminum, steel, and turbine blades are presented.
