Contuitive equations for mechanical properties of cast aluminum AC4C and ADC12 alloys were investigated in the temperature 360°C to eutectic temperature and the strain rate of 5×10-4 to 10-1 per second to obtain fundamental data for deformation behavior of castings. Flow stress was represented in the quadratic form of strain, strain rate and temperature of above mentioned range by the multi-regression method. Tensile strength decreased with increaing in temperature and decreasing in strain rate. Ductility droped abruptly near the eutectic temperature.
