Properties of engineering materials under development applicable in the near future in traffic, medicine and power generating industry
Investigator: prof. RNDr. Ludvík Kunz, CSc., dr. h. c.
Number of Project: 1QS200410502
Agency: Grant Agency of the Academy of Sciences of the Czech Republic
Duration: 01. 01. 2005 - 31. 12. 2009
Verification of mechanical properties of engineering materials which are in advanced stage of basic research and which promise the near future application in engineering practice in enterprises is the main aim of the project. The research isl be focused on high temperature materials for gas turbines and turbochargers (superalloys and intermetallics), metallic biomaterials for surgical implants (stainless steels, Ti-alloys, NiTi alloys) and new steels for railway traffic. The results and knowledge of basic research are applied to the particular engineering items, verified in sufficient extent, published and prepared for direct application in engineering practice in enterprises which have certified an expression of interest on research results.
