Methods for fabrication of parts from bulk low-cost interface-defined nanolaminated materials

摘要

This present invention describes interface-defined nanolaminates (IDnLs), which are novel nanolaminate materials fabricated from metals and ceramics, and new methods for fabricating these IDnL materials, including new methods for manufacturing high aspect ratio parts comprising IDnL materials according to the present invention. IDnLs are fundamentally different from ordinary laminates in that their properties are defined by the interfaces between the layers rather by the properties of the bulk materials comprising the individual layers. In contrast to superlattice materials, IDnLs may be made thermally stable due to the wide selection of interface-defining materials, which allows judicial use of equilibrium phase diagrams. The degree of interface coherency in IDnLs may be varied to optimize material properties. In addition, IDnLs may be manufactured inexpensively in bulk, industrial quantities and large sizes by the techniques disclosed in this invention.
