摘要

Microstructural changes of a near fully lamellar γ-TiAl base alloy after heating shock and ageing treatment have been investigated. After infrared heating treatment, the coarse and fully lamellar (FL) structure (lamellar cluster size 300 μm, lamellar spacing 1.3 μm) of as-cast γ-TiAl base alloy became a substable structure with extreme fine lamellar spacing (140 nm) as well as flat lamellar boundaries which could be transformed to a stable, fine, fully lamellar microstructure (lamellar cluster size 40 μm) after 1260°C, 6 h ageing treatment.
