Creep-Induced Phase Instability and Microstructure Evolution of a Nearly Lamellar Ti–45Al–8.5Nb–(W, B, Y) AlloyXuyang Wang1,Jieren Yang1,2,Rui Hu1,2,Zitong Gao1,Jinguang Li1,Hengzhi Fu11. State Key... University摘 要:Microstructure degradation and stress-induced transformation of a high Nb-containing TiAl alloy with nearly lamellar microstructure during creep......
-etched sample FL microstructure is also successfully obtained in TAN4, but its lamellar colonies become coarse (Fig.5(a)). Their sizes are within 100-200 μm. Similarly, the deformation... in TiAl phase matrix. At 1 350 ℃, only a few lamellar colonies form and the diffusion of Nb element is incomplete. With the increase of hot pressing temperature, the microstructure will be more homogeneous......
