Additive manufacturing promising with AF-9628, a high

Aug 22, 2019 · AF-9628 is a steel alloy developed by AFRL's Dr. Rachel Abrahams that offers high strength and toughness. The formula, nicknamed Rachel's steel, costs less than some other high performance steel alloys including Eglin Steel and HP-9-4-20; however, it is more expensive than common grades used in conventional munitions. Advanced High Strength Steel - MatmatchAdvanced High Strength Steel (AHSS) refers to steel grades with an excellent combination of ductility, toughness and strength that allows them to be machined into thinner sheets delivering superior tensile strength to traditional steel. Steel is a material that has been used globally and has been a major factor in advancing societies and economies.

Advanced High-Strength Steel (AHSS) Definitions

Todays AHSS for Automotive. Advanced High-Strength Steels (AHSS) are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes.Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties. Advanced High-Strength SteelsNew Types on the Block Replacing high-strength and very-high-strength steels with the firms multiphase steels (MP800 and MP800 HY), as well as a dual-phase steel (DP 980 HY, 675 MPa yield strength, 1010 MPa tensile strength), sliced the weight of the axle by 21 percent, with a negligible cost increase. arcelormittal

    High hardness and toughness guaranteed - Voestalpine

    High hardness is achieved by annealing steels with relatively high carbon content in the heat-treating furnace and then quickly water-cooling them in the quencher. This is the conventional technology. The high carbon content makes steel hard, but also brittle, and high degrees of toughness High-Strength Low-Alloy Steels - ASM Internationalenhance strength, toughness, formability, and weldability Acicular ferrite (low-carbon bainite) steels,which are low-carbon (less than 0.05% C) steels with an excellent combination of high yield strengths, (as high as 690 MPa, or 100 ksi) weldability, formability, and good toughness Dual-phase steels,which have a microstructure of martensite dis-
