The influence of modification with rare earth elements (RE) on the structure and mechanical properties of alloy ZnAl22Cu3 is presented in the paper. ZnAl22Cu3, ZnAl22Cu3SiM and ZnAl22Cu3Si (modified alloy) alloys were tested. ZnAl22Cu3Si and ZnAl22Cu3 alloys were characterized with heterogeneous, fine-grained, dendritic structure. The structure of the alloy ZnAl22Cu3SiM was much more homogeneous. It was found that the addition of silicon reduces the tensile strength. Addition of rare earth elements to the alloy with silicon resulted in the re-growth of melt strength of alloy. It was also found that the modification performed by using of rare earth elements increases the hardness of the alloy.

W pracy przedstawiono wpływ modyfikacji pierwiastkami ziem rzadkich na strukturę i właściwości mechaniczne stopu ZnAl22Cu3. Badaniom poddano stop ZnAl22Cu3, ZnAl22Cu3Si oraz ZnAl22Cu3SiM (stop modyfikowany). Stopy ZnAl22Cu3 oraz ZnAl22Cu3Si charakteryzowały się niejednorodna, drobnoziarnista, dendrytyczna struktura. Struktura stopu ZnAl22Cu3SiM była natomiast w znacznie większym stopniu jednorodna. Badania wykazały, ze dodatek krzemu powoduje obniżenie wytrzymałości na rozciąganie. Dodatek pierwiastków ziem rzadkich do stopu z krzemem powodował natomiast ponowny wzrost wytrzymałości stopu. Modyfikacja pierwiastkami ziem rzadkich wpływa również na zwiększenie twardości stopu.
