Research Abstract |
Two forming processes, they were a high temperature compression and a compressive torsion forming for powder metal, were investigated in order to develope new processes for simultaneous joining and forming of partially reinforced metal matrix composite products. The results were as follows ; <<High temperature compression process>> 1. An aluminum matrix composite and an aluminum alloy can be simultaneously joined and formed together in one body. 2. The joining strength of the specimen deformed by a plane strain compression was higher than that by an uniaxial compression. The higher reduction than 50% and higher temperature than 673K were required to get suitable joining strength. 3. The joining strength was increased about twice by subsequent T6 heat treatment. <<Torsional compression forming process>> 1. Partially particle reinforced metal matrix composite products can be fabricated by consolidation of an alloy powder and a mixture with ceramic particle. 2. It is possible to consolidate and join a metal matrix composite on a conventional alloy metal. 3. In both processes, the material with lower flow stress was easily deformed and consolidated.
