THE GRAIN BOUNDARY INTERNAL FRICTION IN A POROUS ULTRA-FINE GRAINED MATERIAL
https://doi.org/10.15518/isjaee.2015.17-18.014
Abstract
This work is devoted to theoretical research of structure materials with submicro size of grain. The mathematical model of internal friction in a porous ultra-fine grained material is suggesting. On this article is considering reshaping the pores by means of the diffusion. There are derived expressions for the speed of intergranular slip, the internal friction in the form of the Debye peak and the relaxation time in this work.
