摘要： A physical vapour deposition apparatus for pre-coating fibres of a reinforcement material with a predetermined thickness of matrix metal prior to consolidation to yield a metal matrix composite material comprises: at least one evaporation crucible; a heater for heating a charge of metal in the at least one evaporation crucible to a temperature at which an appreciable vapour pressure is generated and a flux of metal vapour is evolved; a powered take-up device for drawing the reinforcement through the apparatus, and a guide mechanism for guiding the reinforcement repeatedly through the vapour flux, and to effect twisting of the reinforcement about its longitudinal axis after each successive pass through the vapour flux by an amount which is a fraction of 180.degree.. The guide mechanism comprises a pair of multi-pass transfer rollers each having a multiplicity of concentric fibre-receiving grooves formed on its surface. The transfer rollers are positioned above the evaporation crucible or crucibles and spaced apart from each other with their rotational axes parallel. At least one of the transfer rollers comprises a plurality of independently-rotatable sub-rollers.

摘要： A metal matrix composite material made of a fiber reinforcement having a coating of gadolinium and gadolinium boride, preferably as discrete layers, each having a thickness of 1 to 6 microns. This composite is made by coating reinforcing fibers with gadolinium using a deposition technique, further coating the fibers with gadolinium boride by a deposition technique and then consolidating the coated fibers into a metal matrix to form the metal matrix composite.

摘要： An alloy based on titanium and containing 0.5 to 30% by weight of magnesium, calcium or lithium is produced by vapor quenching to yield a metastable solid solution of solute in titanium. Exemplified alloys containing magnesium have age hardening or solution strengthening characteristics. Vapor quenching enables these alloys to be produced despite the differences in melting temperature between solute and solvent by separate vaporization of each of the species and mixing in the vapor phase. This method provides a route to achieving rapid solidification microstructures unobtainable by other rapid solidification methods. Preferred alloys comprise Ti with 1-15% or 3-7% by weight of magnesium. The alloys may contain other strengthening ingredients currently used in titanium alloys.

摘要： Precursors for metal matrix composites are produced by coating a long fibre ceramic reinforcement with alternating layers of dissimilar species of matrix materials to an aggregate thickness sufficient to yield the intended matrix volume fraction in a consolidated product without additional material. This duplex coating of fibres is performed by vapor phase deposition comprising vapor condensation, sputtering or chemical vapor reaction. The precursor includes an aggregate coating of at least 5% of fibre diameter, preferably at least 20%. Various duplex systems are disclosed, each having one component significantly more frangible than the other to render damage tolerant properties to the resultant metal composite.Product materials are produced from the duplex matrix coated fibres by consolidation of an assembly of coated fibres under conditions of elevated temperature and pressure to cause inter-fibre matrix flow and bonding of matrix materials.
