Abstract

The second phases in Ti40 (Ti25V-15Cr-0.2Si) burn resistant titanium alloy are studied. The higher solution temperature, the more second phases in Ti40 alloy. There are not second phases if the solution temperature is below 850°C, while there are rod-like α and little Ti₅Si₃ phases if temperature is over 850°C. α, Ti₅Si₃ α″ phases emerge after Ti40 solution at 910°C followed by aging at 600°C, while only Ti₅Si₃ phases emerge after solution at 860°C followed by aging at 600°C. The effect of the second phases on properties at RT are not obvious. There are different shapes of α and Ti₅S₃ precipitates after Ti40 alloy exposure at 540°C for 100 h, which decreases the thermal stability.
