Description
  • Intermetalická slučenina obsahující cca 50 at.% Ni a 50 at.% Ni je považována za standardní slitinu s jevem tvarové paměti. Základní požadavek na metalurgii těchto material spočívá ve striktním dodržování chemického složení slitiny, což představuje základní podmínku pro přípravu slitiny s žádanými transformačními charakteristikami. Tyto slitiny bývají nejčastěji připravovány pomocí plazmového tavení nebo vakuového indukčního tavení. Technologie přípravy má rovněž významný vliv na výslednou mikrostruktury finální slitiny. Pro úspěšné použití je nezbytné dosažení homogenní mikrostrukrutry. Po procesu přípravy v grafitovém kelímku mikrostruktura slitiny velmi často obsahuje nežádoucí částice jako TiC a Ti4Ni2O. Tento článek je zaměřen na přípravu Ni-Ti slitin s jevem tvarové paměti ve vztahu k mikrostruktuře. Pozorování a hodnocení mikrostrukturních charakteristik bylo realizováno pomocí světelné, elektronové a transmisní elektronové mikroskopie. (cs)
  • Intermetallic compound containing approx. 50 at. % Ni and 50 at. % Ti is considered to be a standard shape memory alloy. The basic requirement to metallurgy of these advanced materials is strict adherence to chemical composition of the alloy, which is the main condition for obtaining of the alloy with the required transformation temperatures. These alloys are most commonly prepared by plasma melting or vacuum induction melting. The technology of preparation of the alloys have significant effect on microstructure of prepared alloy. For successful use it is necessary to obtain homogenous microstructure. After preparation in graphite crucible, microstructure often contains undesirable particles as TiC and Ti4Ni2O. This article deals with preparation of Ni-Ti shape memory alloys in relation to the microstructure. Observation of microstructures was realized by light microscopy, electron microscopy and transmission electron microscopy.
