Stability of nickel-base superalloys for turbine disc applications
… stability by promoting the formation of topologically close-packed (TCP) phases, which are deleterious to alloy performance. High $\gamma^\prime$ volume fractions, which are needed to provide high-temperature strength, exacerbate the problem by increasing the concentration of these …

Recrystallisation in Single Crystal Nickel-Based Superalloys
… that deformation occurs at temperatures close to the y' solvus, which is 1250-1310°C for CMSX 4, where dislocations accumulate in the interdendritic areas that are the first to precipitate the y'. On examining the cast surface of CMSX 4, two sources of nucleation for recrystallisation …

Atomistic modelling of precipitation in Ni-base superalloys
… such as carbides, borides, oxides and topologically close packed phases. In this work we have set out to investigate the onset of $\gamma^{\prime}$ ordering in Ni-Al single crystals and in Ni-Al bicrystals containing coincidence site lattice grain boundaries (GBs) and we do this at high …
