are analyzed in terms of the constitutional undercooling criterion. Key words: peritectic reaction; Cu-Ge alloys; directional solidification; microstructure; constitutional undercooling 1 Introduction... in the macroseparation structure. The constitutional undercooling criterion is used to analyze the morphological stabilities of the solidifying peritectic phase and the remelting of the primary phase......
102-103 K/s) provided by copper mold suction casting. It is known that the GFA of an alloy correlates with the ability of its melt to deep undercooling. Previous studies indicated that the melt...Trans. Nonferrous Met. Soc.
