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.

研究了两个形成过程，是高温压缩的，对粉末金属进行了压缩扭转，以开发新的过程，以同时连接并形成部分增强的金属基质复合产品。结果如下; <<高温压缩过程>> 1。铝基质复合材料和铝合金可以同时连接并形成一个体。2。平面应变压缩变形的试样的连接强度高于单轴压缩。要获得合适的连接强度，需要较高的降低大于50％和高于673K的温度。3。通过随后的T6热处理，连接强度提高了两次。<<扭转压缩过程>> 1。可以通过合金粉和与陶瓷颗粒的混合物合并来制造部分颗粒增强金属基质复合产物。2。可以在常规合金金属上合并并连接金属基质复合材料3。在这两个过程中，具有较低流动应力的材料很容易变形并巩固。
