Microstructural stability, phase transformation and mechanical properties of a fully-lamellar microstructure of a Mo-modified high-Nb γ-TiAl alloy

Microstructural instability modes, phase transformation and mechanical properties evolution of a fine-grained fully-lamellar Ti–44Al–6Nb–1Mo−0.3(B, Y) (at.%) alloy were investigated systematically. During isothermal exposure at application temperatures, dramatic discontinuous precipitation of γ and...
