MATHEON-ICM WORKSHOP on Free Boundaries and Materials Modeling - Abstract

Design of modern engineering materials

Novel engineering materials exhibit complexity of the structure at various length scales. A number of structural parameters have an impact on the their properties. Chemical composition, spatial arrangement of phases as well as defects at different length scale influence such properties as: mechanical (strength, hardness), magnetic and thermal (structure stability), etc. In order to design material with desirable properties the structure-properties relationships have to be quantitatively described. This can be facilitated by modern characterization and modelling techniques. In the presentation the special attention will be paid to metallic nanomaterials obtained via different fabrication routes. The methods for quantitative characterization of the structure and properties will be introduced. The main part of the presentation will be dedicated to modelling of the structure-properties relationships. In particular the aspects of strength and thermal stability of nanometals will be addressed. Joint work with Krzysztof J. Kurzydłowski (kjk@inmat.pw.edu.pl).
