    A new technique developed to gain information on the elemental structure of segregation at grain boundaries consists of activating the specimen and electropolishing the fractured surface in small increments. The fracture is along the grain boundaries. The induced activity of the dissolved metal in the etchant gives a quantitative measure of the elements present. The technique should be equally applicable to the study of the diffusion of one element into another or to the study of surface phenomena.

    This paper describes the first measurements made of the segreagtion of manganese and chromium into the grain boundaries of the steel used in turbine forgings.
