Factors affecting the accuracy and precision of quantitative description of materials microstructure
Silesian University of Technology, Department of Materials Science, Krasińskiego 8, Katowice 40-019, Poland
The required properties of structural criteria for materials quality assessment are discussed. An example of the application of various 3D computer simulated models of polycrystalline materials microstructure for assessment of accuracy and versatility of hitherto used methods for the determination of grain volume distribution parameters is presented. It shows that none of these methods ensured the required accuracy and versatility of grain size evaluation at acceptable labour consumption. The new empirical relationships between parameters of distribution of plane section area and grains volume were determined. They are the basis of simple method for grain size estimation.
