The maraging steels are now well known for their desirable combination of high strength and good toughness at room temperature [1–3]. Room temperature tensile strengths up to 350 ksi have been obtained with aged material; however, the fracture toughness is somewhat lowered at these high strengths. Nevertheless, reasonable compromises may be made between these two properties for room temperature applications.
