Characteristic of Fiber Inserted Aluminum Alloy Composite Strip Fabricated Using a Twin Roll Caster

Abstract

Casting of fiber inserted aluminum alloy composite strip was tried using a downward melt drag twin roll caster. In this method, casting of the strip and insertion of the fiber was operated simultaneously. The steel wire with diameter of 0.3mm was inserted into the strip. When roll speed was low, and pouring temperature was high, the fiber inserted the strip could be without gap between the fiber and the strip. The fiber inserted composite strip could be cold rolled. The reduction of the fiber and the strip was almost equal. The gap between the fiber and the strip could be improved by the rolling. Reaction between the fiber and the strip was investigated using EPMA.
