Abstract: Exemplary alloys may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities. Exemplary methods may include conducting additive manufacturing with an atomized alloy powder to generate a manufactured article, where the atomized alloy powder may comprise, by weight percentage, 13.25% to 14.75% chromium; 4.5% to 5.5% nickel; 0.11% to 0.17% carbon; 0.01% to 0.31% titanium; and the balance of weight percent comprising iron and incidental elements and impurities.

Abstract: Functionally graded materials may comprise a graded volume extending between a tungsten-based structure and a steel-based structure, where the graded volume comprises a plurality of additively manufactured layers. At least one of the plurality of additively manufactured layers may comprise a ternary element selected from vanadium and chromium. Some of the additively manufactured layers may further comprise aluminum.
