Influence of Interfaces upon the Self-Diffusion in AZ91 Alloy Reinforced by Saffil Short Fibres

Article Preview

Abstract:

Diffusion of 65Zn in Mg-based alloy AZ91 with short Saffil fibres was studied by sectioning method in the temperature interval 648 – 728 K. The results were compared with those obtained in the measurements made with the same materials without the reinforcement. This enabled to assess the influence of the interfaces between the matrix and the fibres and to evaluate the diffusion characteristics of interface self-diffusion.
