摘要：
Laminar composites were prepared of outer layers of 18Ni (200) maraging steel with various inner layer materials. The composites showed reasonable fabricability in both hot and cold working operations. The materials were weldable, and the composite structure could be continued through the weld zone using conventional welding techniques. Yield strengths on the order of 200 ksi were obtained along with excellent crack stopping ability in impact, fracture toughness, stress-corrosion, and fatigue loading. In general, good combinations of fabricability and crack stopping ability can be achieved through the use of soft, relatively thick internal layers that are well bonded to the outer layers.
