Popis:	(Ti,Al)-type ordered γ’ phase in the commercial nickel-based superalloy Inconel X-750 was investigated using Coincidence Doppler Broadening (CDB) tech-nique. The results obtained are discussed in terms of positron annihilation in two well-defined states: one corresponding to the matrix (γ phase) and a second related to the γ’ precipitates. Between these two aging stages, CDB distributions corresponding to selected intermediate aging treatments could be presented ex-actly, within the experimental scatter, as a linear combination of the γ and γ’ signatures.
