Abstract

A program was developed to predict d-spacings and intensities for peaks of binary phases, using data of the stoichiometric compositions as a basis, and was extended for ternary systems. Predicted data were compared with results from a series of alloys in the Ni-Ru-Al system, spanning the system near 50 atomic % aluminum, to ascertain the extension of the RuAl and NiAl intermetallic compounds into the ternary system. The microstructures mainly appeared cored, and one sample was single phase.

The program enabled easy identification of the peaks, and also allowed comparison of experimental data with predicted ordered and random spectra.
