The steels discussed in this paper are 4330, Eglin steel, and AF 9628 steel. Microsegregation of alloying elements within these materials, which is the tendency

AF-9628 is currently manufactured with both traditional and additive methods, such as laser powder bed fusion. AF-9628 is an Air Force steel alloy developed by AFRL’s Dr Rachel Abrahams, which offers high strength and toughness. The formula to produce the alloy reportedly costs less than other high performance steel alloys, including Eglin Steel and HP-9-4-20, but is more expensive than common grades used in conventional munitions. Awarded by the National Center for Defense Manufacturing and Machining (NCDMM) on Sept.
