Effect of addition of Mo and C on microstructure and properties of TiAl alloys with high Nb content
Original language description
Six grades of TiAl alloy with 7% of Nb and doped with C and/or Mo were prepared. The effect of element addition on microstructure and phase composition was characterized using electron microscopy and neutron diffraction. The alloys had substantially different microstructure. Common feature of all materials were domains with alternating lamellae of ? and ?2 phases. Presence of ordered ?0 phase in the form of islands was observed in Mo containing alloys. The biggest amount of ?0 phase evaluated using neutron diffraction was about 15% for material doped with 2% of Mo. Both SEM and TEM studies confirmed that in alloys containing carbon no ?0 phase was observed. Microstructure of alloys with both Mo and C contained large islands of ? phase and small islandsof ?0 phase often connected to lamellae of ? and ?2 phase. Monotonic properties were measured at ambient and elevated temperature. Tensile elongation of all alloys was rather limited at both temperatures however some materials exhibited
