DEFINITION

Classification: 428/567

(under subclass 546) Subject matter containing elongated elements in a defined relationship to each other (e.g., parallel) or in which matrix or continuous phase of one metal (usually a consolidated powder material having an interconnected "void" structure) is interengaged with a matrix or continuous phase of a different metal. The different metal is usually a nonparticulate, impregnating metal.

(1) Note. An elongated element is one having one dimension significantly larger than its other dimensions, e.g., fibrous, needle-like, rod-like, etc.

(2) Note. A mere elongation of the entire product is not sufficient for placement herein.

539.5, for stock-material* having a metal continuous phase interengaged with a nonmetal continuous phase.

545, for the product which results when a consolidated metal powder material having an interconnected void structure is only partially impregnated with a nonmetal material.

550, for the product which results when a consolidated metal powder material having an interconnected void structure is only partially impregnated with a different metal. 556, for stock-material* of consolidated metal powder having an interconnected void structure.
