Résumé	IMRI has been developing thin strip casting with a horizontal twin-roll machine. The A356 aluminum alloy was cast. The strip was 3 to 5 mm in thickness and 100 mm in width. The microstructure of the as-cast material was characterized. The secondary dendrite arm spacing (SDAS) was found to vary from 3 to 10 μm close to the wheel surface and at the central zone, respectively. The mechanical properties were determined. The ultimate tensile strength (UTS) and ductility increase with decreasing SDAS while the yield strength is almost constant. The UTS varies from 196 to 233 MPa, the elongation from 7.5 to 16.8% and the value of the yield strength is around 95 MPa. The mean value of the SDAS varies from 6 to 4.32 μm when the speed goes from 7 to 3.4 RPM. Thermal analysis of the process was conducted by reproducing cyclic thermal variation of the roll surface. The heat transfer coefficient was found to be around 30kW/m³K.
