Goal of the study is to elucidate the mechanism by which boron and other solutes affect the ductility and strength of polycrystalline Ni3Al and other ordered intermetallics. The study is part of a BES-sponsored interlaboratory effort to bring various analytical and theoretical methods to bear on this question. The first discussion meeting of the members of this group was held at the Oak Ridge National Laboratory on September 20, 1985. Our initial field-ion microscopy and atom probe microanalysis results on Ni3Al were represented at that meeting. This paper summarizes the results of our study obtained during the first six months of the contract period.
