Characterization of heterogeneities in grain size by network analysis
Autor: Tiago Estrela de Oliveira, Júlio César Dutra
Publikováno v: Materials Characterization. 127:222-230
Heterogeneities in grain size are very common, mainly when phenomena such as abnormal grain growth is taking place. A new method to measure them is put forward. It is based on network analysis in which an adjacent matrix is built from a microstructur
