Alumina/Nickel Laminate Under Thermal Shock Up to 1000 degree C
Abstract
This report results from a contract tasking Technion Israel Institute of Science and Technology as follows: The contractor will investigate a novel laminated material system consisting of thin ceramic layers alternating with thinner metallic interlayers for use as flaps in a gas exhaust afterburner. In this system, the ceramic is the high melting point constituent, possessing high stiffness, high wear and fatigue resistance at elevated temperatures. The metal interlayers provide the needed compliance, ductility, and toughness. The interface should be strong enough to prevent crack deflection and disintegration of the material system when damage occurs. Oxidation resistance of such systems is expected to be good due to the small exposed area of the metallic interlayers. Good fracture toughness of the laminated system (more than an order of magnitude better than monolithic alumina) and R-curve behavior upon mechanical loading is expected.
