Abstract

A cathodic hydrogen charging procedure is described which allows intergranular fracture in boron-doped Ni 3 A1 samples which are normally ductile and do not fracture intergranularly. This has allowed determination of the boron content of the grain boundaries. It is shown that the hydrogen charging has no influence on the measured boron content. © 1990, American Vacuum Society.
