Method for monitoring the residual compressive stresses of components in a shot peening process

摘要

The invention relates to a method for monitoring the resulting internal compressive stresses of components (18) in a shot peening process. The method comprises the steps of introducing (A) specimens (22) into the shot peening process, which are processed in addition to the components (18), measuring (B) the magnetic parameters of the specimens (22) after the shot peening process, and the Determination (C) of the absolute measured values of the residual compressive stresses stored for the magnetic parameters on the basis of calibration data.
