Author Description

This book contains selected contributions presented at the 15th conference "Contribution of Metallography to Production Problem Solutions" held on 21 - 23 September 2021 in Mariánské Lázně, Czech Republic. The conference was focused on the application of metallography in industrial practice - for the solution of production problems, elucidation of premature failure of machine components and constructions during service, breakdowns or accidents. In addition, some results of new research projects which could improve manufacturing technology or the quality of machine products are presented. Individual papers deal with failure causes and fracture mechanism, insufficient material properties and incorrect function of the components. Using metallographic analyses, which include light and electron microscopy, spectroscopic methods, and physical methods for the detection of defects, material structures are investigated. Results are correlated with material properties, and recommendations for production improvement are given.
