The microstruture of the Cu-Pb monotectic system which solidified under various cooling conditons and gravity coefficients were analyzed. The so called "Homogenization number" which was comparing the relative influences of gravitational and Marangoni force, nucleation and growth of liquid (or solid) particles, natural convection and dimension of specimen on morphological behaviors of solidified monotectic system could be used successfully to rationalize the microstructures. Under one atmosphere condition, the macrosecregation between Cu and Pb occurred mainly due to the sedimentation (or cooling) time. On the other hand, the gravitational force (Stoke`s force) was the major considering parameter to homogenize the specimen under microgravity condition.
