Název v původním jazyce

Microstructure of Ti-46Al-5Nb-1W alloy after directional solidification

Popis výsledku v původním jazyce

Intermetallic alloys based on g-TiAl two-phases alloys are sought-after materials for assumed applications in aerospace and automotive industries. Their favorable properties, such as low density and good corrosion resistance, are accompanied on the otherhand by low toughness and very difficult metallurgy. One of the possibilities to improve the toughness of Ti-46Al-5Nb-1W (at.%) alloy consists in change of their microstructure into lamellar microstructure, which can be reached moreover by directional solidifcation. This experiment is described in this paper. Samples of the Ti-46Al-5Nb-1W (at.%) alloy were prepared by plasma melting. Then the samples were remelted in vacuum-induction furnace becouse of the low homogenity. Cast samples were subjected todirectional solidifcation. Cooling rates were constant and ranged from 20 mm/h to 425 mm/h. Directional solidification has been accomplished in ceramic tubes made of corundum - Al2O3. The samples were studied by metallographic analysis.
