Effect of minor additions on the formation of TCP phases in modified RR2086 SX superalloys

The effect of minor additions (C and Hf) on the formation of topologically closed-packed (TCP) phases in single crystal (SX) superalloy RR2086 has been investigated. The base RR2086 and the modified RR2086 were exposed at 950 °C for 200–2000 h. It was found that both alloys were very stable in terms...
