  • The benefit of the glassy state of reinforcing particles for the densification of aluminum matrix composites 
    Kvashnin, Vyacheslav I.; Dudina, Dina V.; Ukhina, Arina V.; Koga, Guilherme Yuuki; Georgarakis, Konstantinos (MDPI, 2022-05-07)
    In metallic glass-reinforced metal matrix composites, the glassy phase can serve a dual purpose: (i) it can behave as soft binder and porosity remover during consolidation; and (ii) it can act as the hard reinforcing phase ...
  • Interaction between Fe66Cr10Nb5B19 metallic glass and aluminum during spark plasma sintering 
    Dudina, Dina V.; Bokhonov, Boris B.; Batraev, Igor S.; Amirastanov, Yusif N.; Ukhina, Arina V.; Kuchumova, Ivanna D.; Legan, Mikhail A.; Novoselov, Aleksey N.; Gerasimov, Konstantin B.; Bataev, Ivan A.; Georgarakis, Konstantinos; Koga, Guilherme Yuuki; Guo, Yaofeng; Botta, Walter José; Jorge, Alberto Moreira (Elsevier, 2020-08-28)
    In the area of metal matrix composites, novel reinforcing options are currently being evaluated. Particles of amorphous alloys present an interesting possibility to reinforce soft metals. In the present work, the interaction ...
  • Microstructure and mechanical properties of composites obtained by spark plasma sintering of Al–Fe66Cr10Nb5B19 metallic glass powder mixtures 
    Dudina, Dina V.; Bokhonov, Boris B.; Batraev, Igor S.; Kvashnin, Vyacheslav I.; Legan, Mikhail A.; Novoselov, Aleksey N.; Anisimov, Alexander G.; Esikov, Maksim A.; Ukhina, Arina V.; Matvienko, Alexander A.; Georgarakis, Konstantinos; Koga, Guilherme Yuuki; Jorge, Alberto Moreira (MDPI, 2021-09-15)
    At present, metallic glasses are evaluated as alternative reinforcements for aluminum matrix composites. These composites are produced by powder metallurgy via consolidation of metallic glass-aluminum powder mixtures. In ...
  • Reactivity of a glassy and a crystalline Fe66Cr10Nb5B19 alloy towards aluminum during sintering: a comparative study 
    Kvashnin, Vyacheslav I.; Dudina, Dina V.; Bokhonov, Boris B.; Petrov, Sergey A.; Ukhina, Arina V.; Georgarakis, Konstantinos; Coury, Francisco Gil; Koga, Guilherme Yuuki (Elsevier, 2023-05-26)
    A glassy Fe66Cr10Nb5B19 alloy and its crystalline counterpart consisting of the α-(Fe,Cr), FeNbB and Fe2B phases were spark plasma sintered with aluminum at 570 °C to investigate the interfacial reactions in the systems. ...
