Abstract

The effect of the shear modulus, size and dispersion of second phase particles on rate of growth of fatigue cracks in two-phase materials is determined using the kinetic theory approach. The results obtained explain the experimental observations in pearlitic steels.

Résumé

L'étude du module de sélectivité de la dimension et de la disposition des particules de face secondaire sur la croissance de fissure de fatigue dans des matériaux comportant 2 faces a été déterminée en utilisant une théorie cynétique. Les résultats obtenus rendent compte des observations expérimentales effectuées dans les aciers perlitiques.
