The paper deals with an application of drilling method in order to determine the residual stresses in big forgings for turbine rotors and railway axles. Residual stress was measured on two forgings of both cases having different heat treatment. Both pieces were identically heat treated by hardening and tempering. Then one piece from both cases was annealed in order to eliminate residual stress. The measuring procedure and the experiment results is described in the contribution. The reason for these experiments was evaluation of impact of different treatment on the level of the induced residual stresses.
