Phase-diagram study of alloys in the iron-chromium-molybdenum-nickel system

Abstract

Alloys in the iron-chromium-molybde num-nickcl syste m were examined after qu enching from 2,200°, 2,000°, 1,800°, 1,650°, and 1,500° F. Composit ional l imi ts of s tability of se ven phases were summarized in diagram s. F e, Mo was foun d. to be a stable phase; and a ternary phase, not previou sly r eported, was identifi ed to hav e the approximate composition of 4 p ercen t of chromium, 53 p ercent of iron, and 43 p er ce nt of molybdenum.
