ABSTRACT:
An austenitic steel alloy has a composition of about 6 to 13 percent aluminum, 20 to 34 percent manganese, 0.2 to 1.4 percent carbon, 0.4 to 1.3 percent silicon, and the balance essentially iron. The relative quantities of the foregoing elements are selected from these ranges to produce a volume percent of ferrite structure in the alloy in the range of about 1 percent to about 8 percent. The volume percent of ferrite is determined by the empirical formula
