Figure 9. Typical γ/γ’ microstructures (light green color arrow represents γ phase; orange color arrow represents γ’ phase) of the 6Ti4Cr3Ta1Mo alloy after aging in the temperature range from 900 to 1,050 °C for different durations from 25 to 400 h. (A) 900 °C; (B) 950 °C; (C) 1,000 °C; (D) 1,050 °C. 1: 25 h; 2: 100 h; 3: 200 h; 4: 400 h.
