    • FRACTURE BEHAVIOR OF FeAlSi INTERMETALLICS 

      Autor: Čech, Jaroslav; Haušild, Petr; Karlík, Miroslav; Nová, Kateřina; Průša, Filip; Novák, Pavel; Kopeček, Jaromír
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The study is devoted to the intermetallic alloy FeAl20Si20 (wt.%) with the potential applications in high temperature aggressive environments. The samples of the same chemical composition were prepared by spark plasma ...

    • INDENTATION SIZE EFFECT IN HIGH PRESSURE TORSION PROCESSED HIGH ENTROPY ALLOY 

      Autor: Haušild, Petr; Čížek, Jakub; Čech, Jaroslav; Zýka, Jiří; Kim, Hyoung Seop
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      High entropy alloy HfNbTaTiZr in as cast conditions and after high pressure torsion straining was characterized by nanoindentation. The length-scale dependent material response (indentation size effect) was characterized ...

    • MECHANICAL PROPERTIES OF FORGED TUNGSTEN HEAVY ALLOYS 

      Autor: Kovářík, Ondřej; Čech, Jaroslav; Čapek, Jiří; Hajíček, Michal; Klečka, Jakub; Siegl, Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Tungsten heavy alloys are composite materials containing spherical tungsten particles embedded in binder matrix. Their excellent mechanical properties can be further improved by rotary forging. This paper aims to gain ...
