Abstract: The SiCp-A356 composite strips of 2~5mm thick were cast by a twin roll caster. The effects of the stirring process, casting speed and strip thickness on the particulate distribution, microstructure and tensile properties of the as-cast strips were investigated. It is shown that both the stirring process and the higher casting speed must be used in order to allow the production of an as-cast structure consisting of a uniform SiC dispersion in the strips, which exhibite good surface appearance and very little edge cracking.
