摘要： The fracture resistance of titanium alloy matrix composites is increased by one of two methods. One method comprises the steps of consolidating a titanium alloy-fiber preform under suitable conditions to provide a metal matrix composite and thermally treating the thus-prepared composite at a temperature above the beta-transus temperature of the alloy for a brief time. In the second method, a composite having increased fracture resistance is produced by consolidating an alloy-fiber preform at a temperature above the normal consolidation temperature for a time less than the normal consolidation time.

摘要： A method to produce high temperature oxidation resistant metal matrix composites by fiber diameter grading, which comprises the steps of (a) laying up an alloy/fiber preform consisting of a plurality of alternating layers of metal alloy and fibers and (b) consolidating the preform under suitable conditions, wherein the layers of fibers in the preform are graduated so that fiber density is lower nearer what will become the exposed surface of the composite and higher toward the interior of the composite. The difference in fiber density is achieved by spacing the near-surface fibers further apart than the interior fibers.
