T1 - A vacancy model for pore annihilation during hot isostatic pressing of single-crystal nickel-base superalloys T2 - Inorganic Materials: Applied Research N2 - An improved diffusion model is proposed for pore annihilation during HIP of single-crystal nickel-base superalloys. The model assumes the pore dissolution by emission of vacancies and their sink to the low angle boundaries. Calculation, considering distribution of the pore sizes, predicts the kinetics of pore annihilation similar to the experimental one. PB - Pleiades Publishing, Ltd.
