Abstract

The short fiber reinforced aluminum composite material was fabricated by the stirring method, and extruded at high temperature at various extrusion ratios. The hot extrusion load of volume fraction 15% metal matrix composites and base alloy A17075 has been compared. The fiber length distribution, fiber breakage and fiber orientation are investigated to determine the fiber behaviour before and after hot extrusion. The tensile strength of the hot extrusion billet was experimentally determined for different extrusion ratios, and compared with theoretically calculated strength.
