Influence of a rich sulphur atmosphere on the phase development and kinetic behaviour of differentially processed RNT650 γ - TiAl alloys

Journal of Materials Research and Technology, 2023
The influence of sulphur atmosphere on conventionally cast (CM) and on electron beam melted (EBM) γ - TiAl RNT650 alloy exposed to a 1% (vol.) H2S – air atmosphere at 650 °C for 500 h was investigated. The material produced by CM showed a lower mass gain
