摘要：
A description is given of a reliable and reproducible etching technique to determine the amount and distribution of the gamma prime precipitate (Ni//3Al) in nickel base alloys. This includes sample preparation, electropolishing, electron microscopy, and the results obtained with two alloys containing, respectively, about 65 and 40 vol% of gamma prime . Known pitfalls in electroetching and their avoidance are discussed.
