Abstract

The phase boundaries of the Fe-Cr-Mo ternary system have been determined at 1200°F (650°C). The method used for locating the phase boundaries consisted of measuring lattice parameters of the various phases and drawing the parameter contours and the tie lines in the one-phase and two-phase regions, respectively. The brittle σ and ∈ phases extend over a major portion of the diagram. The largest one-phase solid solution region is located near the chromium corner of the diagram.
