Technical Information


  1. 1.

    The effect of core properties on the impact-fatigue resistance of carburized samples differs in relation to the design of the sample (with or without a stress concentrator) and the stress level.

  2. 2.

    For samples (machine parts) without a stress concentrator an increase of core hardness leads to an increase of resistance to impact-cyclic loads at low stress levels. At high stresses there is almost no difference in the impact-fatigue resistance.

  3. 3.

    With a stress concentrator the impact-fatigue strength is high only with high ductility of the core.
