In the frame of a European Thematic Network the feasibility of photothermal steel hardness measurement was studied by joint research activities of scientific institutes and industrial enterprises. The gap between mechanical hardness and thermal conductivity was bridged by careful microstructure investigations and by using calibration curves. The measuring conditions for successful photothermal hardness depth profiling were studied. Novel inversion techniques have been applied for depth profile retrieval.
