Abstract:
The microstructural stability of fully lamellar γ-TiAl alloy was studied under thermal exposure at 750, 850 and 950 °C for 3400 h. The microstructure analysis shows that the most dominant change in the microstructure was that the α2 lamellae thinned gradually and thinning was more pronounced with increasing temperature and with increasing time.
