W pracy przedstawiono wyniki badań wskazujące, że Cr, Mo, W i Co tworzą fazę Si(Cr, Mo, W), która stanowi podkładkę krystalizacji fazy beta. Dodatki Cr, Mo, W i Co tworzą również złożone fazy międzymetaliczne Al(Cr, Mo, W, Co, Mg, Ni, Fe, Si), Al(Co, Cu, Fe, Si) oraz Al(Co, Ni, Fe, Si) występujące w fazie alfa.
The paper presents results of the research on unidirectional crystallization of unmodified and modified Al-Si alloys. Relation between interlamellar (interfibre) spacing lambda, undercooling delta T and growth rate nu has been established by the use the Bridgman type device for unidirectional crystallization. It has been observed that the increase on growth rate nu results in the decrease of value...
