Journal ArticleDOI
Temperature dependence of trapped magnetic field in MgB2 bulk superconductor
R. V. Viznichenko,A. A. Kordyuk,G. Fuchs,K. Nenkov,K.-H. Muller,Tetiana Prikhna,Wolfgang Gawalek +6 more
TL;DR: In this paper, the temperature dependencies of the trapped magnetic field have been calculated for two MgB2 samples prepared by two different techniques: the high-pressure sintering and the hot pressing.
Journal ArticleDOI
Synthesis Pressure–Temperature Effect on Pinning in MgB2-Based Superconductors
Tetiana Prikhna,Michael Eisterer,Wolfgang Gawalek,Artem Kozyrev,H. W. Weber,Vladimir Sokolovsky,Xavier Chaud,Jacques G. Noudem,Tobias Habisreuther,Viktor Moshchil,Myroslav Karpets,Tetyana Basyuk,Valeriy Kovylaev,Jan Dellith,V. B. Sverdun,Roman Kuznietsov,Christa Shmidt,T. Vitovetskaya,L. O. Polikarpova +18 more
TL;DR: In this paper, the volume pinning force increases with increasing synthesis or sintering pressure (0.1 MPa-2 GPa), while it stays practically unchanged in those prepared at low temperature (800-°C).
Journal ArticleDOI
Structure and Properties of WC–Co Composites with Different CrB2 Concentrations, Sintered by Vacuum Hot Pressing, for Drill Bits
B. T. Ratov,M. O. Bondarenko,V. A. Mechnik,V. V. Strelchuk,Tetiana Prikhna,V. M. Kolodnitskyi,Andrii Nikolenko,P. M. Lytvyn,I. M. Danylenko,Viktor Moshchil,Edwin Gevorkyan,A. S. Kosminov,A. R. Borash +12 more
TL;DR: In this article, a comprehensive study of composites using conventional methods of testing mechanical properties, combined with digital optical microscopy, transmission microscopy and scanning atomic force microscopy was performed.
Journal ArticleDOI
A new MAX phases-based electroconductive coating for high-temperature oxidizing environment
Tetiana Prikhna,Orest Ostash,A.S. Kuprin,V. Ya. Podhurska,T. B. Serbenyuk,Edwin Gevorkyan,Miroslaw Rucki,Wojciech Zurowski,Wojciech Kucharczyk,V. B. Sverdun,Myroslav Karpets,Semyon Ponomaryov,B. D. Vasyliv,Viktor Moshchil,M. A. Bortnitskaya +14 more
TL;DR: In this paper, the characteristics of highly dense Ti-Al-C composite bulks and vacuum-arc deposited 6-μm thick coatings before and after heating at 600°C in air for 1000h were compared.
Journal ArticleDOI

Tetiana Prikhna,Wolfgang Gawalek,Ya. M. Savchuk,Nina Sergienko,Viktor Moshchil,M. Wendt,Matthias Zeisberger,Tobias Habisreuther,V. B. Sverdun,Shi Xue Dou,Sergey Dub,Vladimir S. Melnikov,Ch. Schmidt,Jan Dellith,P.A. Nagorny +14 more
TL;DR: In this article, the authors showed that adding Zr can increase critical current density (jc) of synthesized at 2 GPa and 750-800 °C MGB2 in the same manner as adding Ta or Ti.
