Abstract:
A process for the manufacture of a composite material comprising a matrix component having one or more metals or alloys selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W and Re; and a reinforcing component selected from the group consisting of carbides, borides, nitrides and oxides of the metals Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W or those of the elements Si, B, Al or those of the Rare Earth Elements; whereby the matrix component is provided in the form of foils, sheets and/or wires; said reinforcing component is deposited onto the matrix component as a dense coating with a thickness between 1 &mgr;m and 10 &mgr;m, or to a maximum of 15% of the thickness of the matrix component, whichever is less, and a plurality of said coated foils, sheets and/or wires are assembled and compacted under the action of pressure, or pressure and temperature, with the resulting composite material having substructures which are oriented in parallel and exhibit the essential morphological features of the original matrix component and of the interspersed undeformed, co-deformed or fragmented reinforcing component.
