Abstract

A method for the manufacturing of metallic matrix composites through plastic working is disclosed. In the method, the plastic working charge is in the form of wires, tape or tapes or foil, which is the first component being covered with the second component or components with granulation less than 100 μm, after which they are connected by reciprocal surface contact, forming weaved bundles, and then the connected elements which form the charge material advantageously undergo initial rolling or drawing and in all cases the principal process, which is extrusion performed on a rolling mill with circumferential grooves, where between rollers a closing matrix is placed, rotating in reverse to its axis by an angle of ±20° advantageously ±12°, with a frequency up to 50 Hz, advantageously 15 Hz.
