Journal ArticleDOI
Yield strength increase of a CoCrNi medium entropy alloy by interstitial nitrogen doping at maintained ductility
Igor Moravcik,Igor Moravcik,Hynek Hadraba,Linlin Li,Ivo Dlouhy,Dierk Raabe,Zhiming Li,Zhiming Li +7 more
TL;DR: In this article, the authors show that interstitial nitrogen doping improves the tensile properties of a CoCrNi alloy and show that the effect of nitrogen doping can be seen in terms of the simultaneous increase of the lattice friction stress and of the Hall-Petch coefficient.
Journal ArticleDOI
Mechanical and microstructural characterization of powder metallurgy CoCrNi medium entropy alloy
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
Effect of heat treatment on microstructure and mechanical properties of spark plasma sintered AlCoCrFeNiTi0.5 high entropy alloy
TL;DR: In this article, the synthesis and heat treatment on non-equiatomic AlCoCrFeNiTi0.5 high entropy alloy with a composite structure reinforced by TiC nanoparticles was investigated.
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.
