Abstract
Metal mold micron scale precision casting technology was developed successfully, and three-dimension complicated microgear castings in micron scale were produced. Evolvement regularity of microgear castings were observed by optical microscope and scanning electron microscope. Compared with conventional casting, microcasting is characterized by typical nonequilibrium solidification, for example, its grain size can be refined significantly, eutectic structure is transformed from lamellar morphology to rod eutectic, and the ratio of primary phase is increased. This kind of microstructure can promote mechanical properties of microcasting.
