  • Nitrogen Interstitial Alloying of CoCrFeMnNi High Entropy Alloy through Reactive Powder Milling 

    Moravčík, Igor; Čížek, Jan; Moravčíkova de Almeida Gouva, Larissa; Čupera, Jan; Gubán, Ivan; Dlouhý, Ivo (MDPI, 2019-04-04)
    The present work is focused on the synthesis of CoCrFeMnNi high entropy alloy (HEA) interstitially alloyed with nitrogen via powder metallurgy routes. Using a simple method, nitrogen was introduced to the HEA from the ...
  • Comparison of Electrochemical Methods for the Evaluation of Cast AZ91 Magnesium Alloy 

    Tkacz, Jakub; Minda, Jozef; Fintová, Stanislava; Wasserbauer, Jaromír (MDPI AG, 2016-11-15)
    Linear polarization is a potentiodynamic method used for electrochemical characterization of materials. Obtained values of corrosion potential and corrosion current density offer information about material behavior in ...
  • Crack onset assessment near the sharp material inclusion tip by means of modified maximum tangential stress criterion 

    Krepl, Ondřej; Klusák, Jan (Gruppo Italiano Frattura, 2017-10-01)
    In the case of particle reinforced composites, where the particles are in a form of sharp material inclusions, singular stress concentration exists on each tip of each inclusion. This is due to the geometric and material ...
  • Machinability and properties of zirconia ceramics prepared by gelcasting method 

    Kaštyl, Jaroslav; Chlup, Zdeněk; Šťastný, Přemysl; Trunec, Martin (TAYLOR & FRANCIS LTD, 2019-10-11)
    The machinability of newly developed zirconia ceramics for computer numerically controlled milling (CNC) was investigated. The zirconia blanks were prepared by the gelcasting method and tested in the green and two pre-sintered ...
  • Nondestructive evaluation of the interface between ceramic coating and stainless steel by electromagnetic method 

    Savin, Adriana; Steigmann, Rosina; Iftimie, Nicoleta; Nový, František; Vizureanu, Petrica; Craus, Mihail-Liviu; Fintová, Stanislava (IOP Conference Series, 2016-09-02)
    Protecting coatings as thermal barrier coating (TBC) are used for yield improvement of equipment working at high temperature. Zirconia doped with yttria ceramics are considered a good TBC material due of its low thermal ...
  • Fatigue properties of B1914 superalloy at high temperatures 

    Horník, Vít; Fintová, Stanislava; Šmíd, Miroslav; Hutař, Pavel; Hrbáček, Karel; Kunz, Ludvík (Elsevier B.V., 2020-02-19)
    B1914 is a nickel-based superalloy with an increased amount of B (boron) and C (carbon) to reach an adequate amount of borides and carbides in the cast structure ensuring improved creep properties. However, the influence ...
  • Interaction of fatigue and creep in MAR-M 247 superalloy 

    Horník, Vít; Fintová, Stanislava; Šmíd, Miroslav; Hutař, Pavel; Hrbáček, Karel; Kunz, Ludvík (Elsevier B.V., 2020-02-19)
    Lifetime of MAR-M 247 Ni-based superalloy was experimentally studied under high-frequency cyclic loading (120 Hz) with constant tensile mean stress m = 300 MPa at temperature 900 °C in air. The stress amplitude a was changed ...
