Abstract. In this paper,the effect of rare earth La on microstructures and properties of ZA30 alloy were studied . The result shows that The structure is refined and mechanical properties are improved by adding La to ZA30 alloy,the alloy have best structures and comprehensive mechanical properties when La content is 0.1%; Rich-La phases are metallic compound Cu2La,Al2La and LaZn and precipitate in blocky form ,its number and size increase with La; The abrasive resistance of ZA30 alloy is significantly improved when La is over 0.3%.
