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 β’ C for 200-2000 h. It was found that both alloys were very stable in term

The phase-field method is used to develop a new technique to simulate c 0 precipitation in multicomponent Ni-base superalloys. This technique generates the Gibbs free energy for both the c and c 0 phases from the single function formalism of both phases in the CALP-HAD method without using conventio
First-order phase transitions in nanoparticles (e.g., metal hydride formation) occur via absorption of species from or release to the gas or liquid phase. If the lattice strain is negligible, the uptake corresponding to a new phase exhibits a stepwise rise or drop with increasing or decreasing press
