Název v původním jazyce

Effect of yttrium addition on microstructure of alloy Ti-47Al, prepared by plasma melting and vacuum induction melting

Popis výsledku v původním jazyce

TiAl based alloys are very perspective material thanks to its outstanding properties, such as high specific strength, low density, high modulus of elasticity and resistance to creep. They might replace the currently used materials in many applications inaircraft and automotive industries, but also in other industries. The main reason why it happens only in very limited extent is their brittleness and complicated production of these alloys. Fabrication of TiAl alloys is difficult, because titanium and aluminium are reactive materials. That?s why these alloys are usually prepared in an inert atmosphere. One of possibilities of enhancement of problematic properties of these alloys is influencing their micro-structure by alloying by elements, which influence grain size and reduce dispersion of precipitates (e.g. B, C, Si). Yttrium is one of the elements, which similarly influence micro-structure and properties of TiAl alloys. According to the work [1] it is possible by addition of yttrium
