Theoretical and experimental estimates of the brittle strength of solids produced by compaction of powders

The strength characteristics of pressed-powder compacts are obtained. The fractal structure of the compact samples is described. Complex thermal analysis shows that during compaction of dry powders, interatomic interaction is partially restored. Quantitatively estimates of the theoretical strength o...

Description
Summary:The strength characteristics of pressed-powder compacts are obtained. The fractal structure of the compact samples is described. Complex thermal analysis shows that during compaction of dry powders, interatomic interaction is partially restored. Quantitatively estimates of the theoretical strength of the samples are obtained and a possible mechanism for the propagation of flat cracks is proposed.
