Calculating the hardening factor in GTE ball-hardened components in an ultrasonic field

We present results from research into the fatigue strength of GTE specimens and blades, ball hardened in an ultrasonic field. Using the theory of similarity and dimensional analysis we derive a model for the hardening factor which allows us to select efficient regimes and to refine the calculation of the strength reserve in the production design stage.Translated from Problemy Prochnosti, No. 8, pp. 78–81, August, 1991.
