Abstract
A composite material bonded by an amorphous metal. In one embodiment, a bonded piece is bonded to a substrate by a layer of amorphous metal interposed between the piece and the substrate. In another embodiment, a bonded composite material is formed with pieces of a second phase distributed throughout the volume of an amorphous matrix. In both embodiments, the second component of the composite is preferably a very hard material of low ductility, so that the composite material is useful in tooling applications. The solid composite material is formed by solid state processing, wherein the pieces are placed in contact and then consolidated at a temperature which does not exceed the crystallization temperature of the amorphous metal.
Claims6
A bonded composite material, comprising:
- a substrate;
- a piece of second material having a low ductility;
- and
- a continuous layer of amorphous metal interposed as a matrix between said piece of second material and said substrate, whereby said piece and said substrate are bonded together by the amorphous metal.
