It has been concluded that wide freezing range alloys are more prone to tearing because their shells maintain contact with the mould longer than dilute alloys, resulting in greater friction forces acting on the shell (Emley, 1976; Ohm and Engler, 1989). It was further argued that the more dilute alloys obtain sufficient strength at higher temperatures and are able to pull
