The strip casting process, in comparison to conventional processing, is able to bypass the hot rolling process and is thermally competitive with the conventional process [1]. Metal products which have been processed using the strip casting process include stainless steels [1,2-5], Al and alloys [4,6-11], carbon steels [12-16], Ni base alloy [17], etc. A weaker plastic anisotropy [2], and a microstructure with a chill zone and a variable equiaxed zone in the central region [3] were mentioned for stainless steel produced with a twin-roll process. A superplasticity characteristic was reported for an as-cast duplex stainless steel [5]. Other investigations on the structure of strip cast stainless steel has also been conducted [4, 18]. An icosahedral quasicrystalline phase was found for A13003 alloys, produced by strip casting, after heat treatment [6]. The strip casting process was capable of producing supersaturate Al-Mn-Mg alloys [8]. It was seen that ductility and ultimate tensile strength can be improved using the strip casting process [7], Enhancement in elevated temperature strength was reported for AIMn alloys when produced by strip casting [10]. A theoretical model was provided for discussing the structural variation of strip cast Al 1100, 3000 and 5000 series alloys [11]. A mathematical model incorporating fluid flow and heat transfer was also developed for manipulating the operational parameters for steel casting [19]. Recrystallization of low carbon steel [13], and the possible modification of the micro-structure of strip cast low carbon steel [14] have also been discussed. It was suggested [14] that large grain size and the cool rate of the cast strip are the main reasons for formation of the Widmanstatten ferrite structure of low carbon steel.
