Abstract

The study of the relationships between grain boundary (GB) structure and chemical composition, in bcc and fcc metallic binary alloys, is accomplished via three different techniques: (a) transmission electron microscopy (TEM); (b) atom-probe field-ion microscopy (APFIM); and (c) Monte Carlo computer simulations. TEM is used to determine the five macroscopic degrees of freedom of a GB; APFIM is employed to measure the chemical composition of the interface; and Monte Carlo calculations are utilized to simulate solute-atom segregation at GB's that are studied experimentally in fcc binary metallic alloys. Detailed results are presented for W(Re) and Pt(Ni) alloys.
