摘要：

A method of anode selective electrolysis for phase extracting and isolation of delta-Ni3Nb, gamma' and gamma" phases in Inconel 718 alloy has been proposed. The ratio of volume fraction of gamma" to gamma' phase is taken as a constant equal to 3. (C) 2002 Published by Elsevier Science Ltd. on behalf of Acta Materialia Inc.
