Verification of the trend of MPL variation in fatigue by modern methods

Abstrakt

The paper presents experimental results concerning the variation of microplastic limit (MPL) during fatigue as determined by the measurement of changes in inductance L of specimens made from normalized low-C steel CSN 411375. Some indications have been obtained that MPL varies during fatigue with dislocation density.

This was proved by nano-indentation, X-ray diffraction and transmision electron microscopy. (C) (2014) Trans Tech Publications, Switzerland.
