Journal ArticleDOI
Hot rolling of MWCNTs reinforced Al matrix composites produced via spark plasma sintering
Behzad Sadeghi,Behzad Sadeghi,Pasquale Cavaliere,Ghasem Azimi Roeen,Martin Nosko,Morteza Shamanian,Veronika Trembošová,Štefan Nagy,Niloofar Ebrahimzadeh +8 more
TL;DR: In this paper, the effects of CNT content as well as plastic deformation on the microstructure and mechanical properties of the obtained nanocomposite, were investigated, and the best comprehensive mechanical properties corresponded to the sheet of Al-0.5-wt.% CNT composites thanks to the strong interfacial bonding between Al and CNTs.
Journal ArticleDOI
Solid-state joining of powder metallurgy Al-Al2O3 nanocomposites via friction-stir welding: Effects of powder particle size on the weldability, microstructure, and mechanical property
Martin Nosko,M. Štepánek,P. Zifčák,Lubomir Orovcik,Štefan Nagy,Tomáš Dvorák,Peter Oslanec,Farzad Khodabakhshi,Adrian P. Gerlich +8 more
TL;DR: In this article, solid-state butt-joining of powder metallurgy fabricated Al-Al2O3 nanocomposites was assessed using friction-stir welding (FSW), in which the PM materials were prepared from aluminum powder with different particle size distributions of
Journal ArticleDOI
Structure evolution and mechanical properties of hard tantalum diboride films
Viktor Šroba,Tomas Fiantok,M. Truchlý,Tomas Roch,Miroslav Zahoran,Branislav Grančič,Peter Švec,Štefan Nagy,Vitalii Izai,Peter Kúš,Marián Mikula +10 more
TL;DR: In this article, a wide range of analytical methods are used to completely characterize the chemical composition, structure, and mechanical properties of TaB2-±-x films, and the explanation of the obtained results is supported by density functional theory calculations.
Journal ArticleDOI
Formation of Al/(Al 13 Fe 4 + Al 2 O 3 ) Nano-composites via Mechanical Alloying and Friction Stir Processing
Ghasem Azimi-Roeen,Ghasem Azimi-Roeen,Seyed Farshid Kashani-Bozorg,Martin Nosko,Štefan Nagy,Igor Maťko +5 more
TL;DR: In this paper, a pre-milled hematite+Al powder mixture was introduced into the stir zone generated on aluminum alloy sheet by friction stir processing, and uniform and active milled powder mixture reacted with plasticized aluminum to produce Al13Fe4+Al2O3 particles.
Journal ArticleDOI
Effect of the TiH2 pre-treatment on the energy absorption ability of 6061 aluminium alloy foam
Ľubomír Orovčík,Martin Nosko,Peter Švec,Štefan Nagy,Miroslav Čavojský,Frantisek Simancik,Jaroslav Jerz +6 more
TL;DR: In this article, the effect of long-term oxidation of TiH 2 on foaming kinetics and structure of heat-treatable 6061 alloy foam was investigated with respect to annealing conditions.
