A Phase Diagram for 1 per cent Carbon–Iron Alloys containing up to 16 per cent Nickel

Abstract

DURING the course of an investigation into the austenite stabilization phenomena of iron–nickel alloys containing 1 per cent carbon, it became necessary to obtain some knowledge of the limiting solubility of the carbide in the austenite. There appeared to be no specific information available concerning the phase relationships of such alloys and, due to the promotion of graphitization by high nickel contents¹, a great deal of uncertainty attends the nature of the iron–carbon–nickel ternary system.
