The Study of Extrusion as a Method for Fabricating Metal Matrix Composites,

Abstract

Extrusion has been investigated as a method for fabricating metal matrix composites. The matrix was aluminum and the fibers were discontinuous boron, graphite and stainless steel and -SiC whiskers. Mixtures of aluminum flake and discontinuous fibers were extruded at temperatures exceeding 600C and at extrusion pressures of 30 - 90 ksi. The extrudate showed a high degree of fiber orientation as well as extensive fiber damage. Some strengthening and stiffening were obtained at the 10 v/o loading level. Fiber damage appears to be the major limitation of the powder metallurgy approach to extrusion. (Author)
