Preliminary Investigation on Fractal Metallographs ——Investigation on the Fractal Characters of Grain Size

Jie Zhou

Abstract

Fractal characters of the metallographical structures are analyzed fractal dimensions of grains in the standard photographs are measured. The relation between grain size and fractal dimension is investigated. It is indicated that metal grain can be described quantitatively by fractal dimension, and in grade 1~8, fractal dimension increases as grade does, which is distinct in grade 1~5.
