Abstract

Rotation-Cylinder method (RCM) as a primary manufacturing process and thixoforming as a secondary forming process are discussed. RCM allows the production of U-shaped laminar melt surface with Rankine vortex, thus significantly reducing particle agglomeration and entrapped slags. Thixoforming is of particular interest as a secondary forming process because of the low fluidity of the composites and the significant wear produced on machining tools and extrusion and forging dies. Some indications about mechanical properties of the composites are also presented.
