摘要：

A program is under way to develop a nickelfree austenitic stainless steel for fusion reactor applications. Previous work showed that a stable austenite alloy is possible in a compositional regime of Fe-(20-25)Mn-(12-14)Cr-(0.1-0.25)C. As a base composition for further alloying for strength and irradiation resistance, an Fe-20Mn-12Cr-0.25C composition was chosen. Tensile properties for this base composition were comparable to those of type 316 stainless steel. To improve strength and irradiation resistance, closely controlled quantities of titanium, tungsten, vanadium, phosphorus and boron were added to the base alloy. Various combinations of these alloying elements improved the tensile properties of the new steels relative to type 316 stainless steel in both the annealed and 20% cold-worked conditions. These solute combinations also produced MC and M23C6 precipitation in some alloys during annealing at 1050 and 1150 °C. © 1990.
