Abstract:The effects of RE on mechanical properties and constituent phase distritution, shape and quantity of ZA27 alloy have been studied. The experiment results show that the RE can refine grain and raise mechanical properties; the α phase can change from bar form to branches, ε phase can distribute dispersively; α phase decreases and ε+η phase increases.
Key words: RE; ZA27 alloy, mechanical properties; phase
