"Growing requirements to mechanical and physical properties of materials necessitated search for new suitable structural materials, which would fulfil all the requirements. Intermetallic alloys from the system Ti-Al represent undoubtedly an important area of development of new materials determined for special applications. This paper is focused on the alloy Ti-46Al-5Nb-1W (at. %), on its metallurgical preparation, on influencing its structure by directional crystallisation and on gas contents in the alloy. The alloy was prepared by plasma and vacuum metallurgy. Directional crystallisation took its course by constant rates within the range from 5.56\u00D710-6 m\u00D7s-1 to 1.18\u00D710-4 m\u00D7s-1. The samples were evaluated from metallographic point of view and they were subjected to gas content analysis. Structure of the alloy consists of lamellar grains, in which lamellas a2 and g alternate. Reaction of molten mass with ceramic mold resulted in formation of ceramic, evenly distributed Al2O3 particles." . . . "Distribution of ceramic particles in intermetallic alloy Ti-46Al-5Nb-1W" .
