Abstract

We report in the present paper a practical situation where the use of atomic force microscopy allowed an irrefutable insight in material plasticity for discriminating between different modelling hypotheses concerning the yield stress anomaly of Ni3Al intermetallic compounds with the L12 ordered structure. The contribution of AFM to a better understanding of elementary rate controlling mechanisms as well as collective dislocation motions is highlighted.
