Effects of heat treatments on microstructures of TiAl alloys
文献摘要：
This study aims to investigate the effects of heat treatments on the microstructure of γ-TiAl alloys. Two Ti–47Al–2Cr–2Nb alloy in-gots were manufactured by casting method and then heat-treated in two types of heat treatments. Their microstructures were studied by both optical and scanning electron microscopies. The chemical compositions of two ingots were determined as well. The ingot with lower Al con-tent only obtains lamellar structures while the one higher in Al content obtains nearly lamellar and duplex structures after heat treatment within 1270 to 1185℃. A small amount of B2 phase is found to be precipitated in both as-cast and heat-treated microstructures. They are distributed at grain boundaries when holding at a higher temperature, such as 1260℃. However, B2 phase is precipitated at grain boundaries and in colony interiors simultaneously after heat treatments happened at 1185℃. Furthermore, the effects of heat treatments on grain refinement and other microstructural parameters are discussed.
