Method for fabrication of superplastic composite material having metallic aluminum reinforced with silicon nitride |
摘要 |
A method for the fabrication of a superplastic composite material having metallic aluminum reinforced with silicon nitride includes thoroughly mixing silicon nitride with metallic aluminum, pressure-sintering the resultant mixture, further heating and pressing the sintered mixture, hot extrusion-molding the resultant sintered article, subjecting the molded article, when necessary, to a heat treatment such as the T6 treatment thereby forming a superplastic composite material, and deforming the composite material in a temperature region in which the material exhibits superplasticity.
