Application of a novel method for fabrication of graphene reinforced aluminum matrix nanocomposites: Synthesis, microstructure, and mechanical properties
Mohammad Khoshghadam-Pireyousefan,Roohollah Rahmanifard,Lubomir Orovcik,Peter Švec,Volker Klemm +4 more
TL;DR: In this article, a graphene reinforced aluminium matrix nanocomposite is fabricated through the combination of high energy ball milling (HEBM) and molecular level mixing (MLM) processes followed by spark plasma sintering (SPS) method.
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
Nanocomposite SAC Solders: The Effect of Adding Ni and Ni-Sn Nanoparticles on Morphology and Mechanical Properties of Sn-3.0Ag-0.5Cu Solders
TL;DR: In this paper, the effect of minor additions of Ni, Ni3Sn or Ni3sn2 nanoparticles on the microstructure and mechanical properties of Cu/solder/Cu joints was investigated by x-ray diffraction and scanning electron microscopy.

Journal ArticleDOI
Electrocatalytic activity of Pd-Au nanoalloys during methanol oxidation reaction
Oksana Dobrovetska,Ivan Saldan,Ivan Saldan,Lubomir Orovcik,Dennis Karlsson,Martin Sahlberg,Yuriy Semenyuk,Orest Pereviznyk,Oleksandr Reshetnyak,Orest Kuntyi,I. P. Mertsalo,Roman Serkiz,Bohdan Stelmakhovych +12 more
TL;DR: In this article, gold-enriched bimetallic Pd-Aunano were recommended as catalysts for oxidation processes since they are characterized by the presence of Auδ+ on their surface.
