Statistical Analysis Method of the Grain Structure of Nanostructured Single Phase Metal Materials Processed by High-Pressure Torsion

Abstract:

The statistical analysis method of the grain structure in bulk single-phase metal materials subjected to high-pressure torsion is proposed. The possibility of methods division of mathematical statistics observed in the grain structure materials by their sizes with the several groups identification, having various behavior at further heating is presented. The example of the grain structure analysis on the nanostructured tin bronze is given. The agreement of the received analysis results with experimental data is offered.
