In the Nb-Cr-Ti system, there is a complete solid solution between NbCr{sub 2} and TiCr{sub 2} with a significant range of solubility for the C15 phase and a large two-phase region of bcc and C15. The Nb-Cr-Ti phase diagram (950 C isothermal section) is shown. The initial characterization by transmission electron microscopy (TEM) of the defect structure of an alloy of overall composition Nb{sub 10}Cr{sub 75}Ti{sub 15} is discussed here. Additionally, Atom Location by CHanneling Enhanced MIcroanalysis (ALCHEMI) was employed to examine the site occupancies of the Nb, Cr and Ti in this C15 Laves phase.
