Igor Moravcik,Jan Cizek,Zuzana Kovacova,Jitka Nejezchlebová,Michael Kitzmantel,Erich Neubauer,Ivo Kubena,Vít Horník,Ivo Dlouhy +8 more
TL;DR: In this article, the synthesis and mechanical properties characterization of equiatomic CoCrNi medium entropy alloy (MEA) with spark plasma sintering (SPS) for bulk alloy densification have been utilized.
Journal ArticleDOI
Microstructure and mechanical properties of Ni1,5Co1,5CrFeTi0,5 high entropy alloy fabricated by mechanical alloying and spark plasma sintering
Igor Moravcik,Jan Cizek,Jozef Zapletal,Zuzana Kovacova,J. Vesely,Peter Minárik,Michael Kitzmantel,Erich Neubauer,Ivo Dlouhy +8 more
TL;DR: In this article, the tensile properties of a bulk material produced by a combination of mechanical alloying (MA) and spark plasma sintering (SPS) were characterized for the first time, and the structure of the sample consisted of single-phase FCC high entropy solid solution of extremely fine-twinned grains and oxide inclusions inherited from the original powder feedstock.
Journal ArticleDOI
Synergic strengthening by oxide and coherent precipitate dispersions in high-entropy alloy prepared by powder metallurgy
Igor Moravcik,Larissa Gouvea,Vít Horník,Zuzana Kovacova,Michael Kitzmantel,Erich Neubauer,Ivo Dlouhy +6 more
TL;DR: In this article, the microstructural and mechanical properties of face-centred cubic Ni15Co15CrFeTi05 high-entropy alloy strengthened by nano-sized titanium oxide dispersion and coherent precipitates of Ni3Ti intermetallic phase produced by powder metallurgy were evaluated.
Journal ArticleDOI
Influence of sintering temperature, SiC particle size and Y2O3 addition on the densification, microstructure and oxidation resistance of ZrB2–SiC ceramics
TL;DR: In this article, the influence of sintering temperature, silicon carbide particle size and yttrium oxide addition on oxidation behavior of ZrB2-SiC ceramics was investigated up to 1650°C in static atmosphere.
Journal ArticleDOI
Influence of Ti on the Tensile Properties of the High-Strength Powder Metallurgy High Entropy Alloys
Igor Moravcik,Stepan Gamanov,Stepan Gamanov,Larissa Moravcikova-Gouvea,Zuzana Kovacova,Michael Kitzmantel,Erich Neubauer,Ivo Dlouhy,Ivo Dlouhy +8 more
TL;DR: The results show that Ti increases the strength of the alloys by increasing the average atomic size misfit i.e., solid solution strengthening, and an excellent combination of mechanical properties can be obtained by the proposed method.
