THE INFLUENCE OF INITIAL DEFORMATION ON STRUCTURE AND MECHANICAL PROPERTIES OF P92 STEEL
 Svobodová, M. ; Čmakal, J. ; Horváth, L. ; Chmela, T. ; Sklenička, Václav
The paper deals with materials properties of steel bends. Tubes and pipes, respectively, of P92 steel were hot and/or cold bended. Moreover, the various combinations of tubes/pipes dimensions were chosen. Then, as-bended steel was exposed to a long-term temperature and/or mechanical loading. Investigating the materials behaviour, some structure and mechanical tests on as-exposed bends were carried out. So, this paper summarizes recent results of performed tests including numerical simulations by FEM.

Properties and microstructure of cast nickel-chromium alloys containing tungsten and carbon as alloying elements
 Kudrman, J. ; Sklenička, Václav ; Čmakal, J.
Model fast nickel-chromium alloys containing W and C as alloying elements exhibit markedly better creep resistance than is possible with currently available commercial nickel-chromium alloys. The model alloys are reinforced by primary and secondary tungsten carbides.
