In order to improve electrochemical property of as cast La3MgNi14 alloy,the alloy was annealed at 1 123,1 223 and 1 323 K under 03 MPa Argon atmospheres for 10 h.Microstructures and electrochemical properties of different annealed alloys have been investigated by XRD,SEM and electrochemical experiment.The obtained results show that ascast alloy and alloy annealed at 1 123 K are compose of LaNi5,(La,Mg)2Ni7 and a small amount of LaNi2 phases.There are some LaNi5,(La,Mg)2Ni7 and(La,Mg)Ni3 phases in alloy annealed at 1 223 K.However,LaNi5 and(La,Mg)Ni3 phases became main phase at 1 323 K.Compared by as cast alloy,composition of annealed alloys is more homogeneous,and grains of annealed alloys are coarsened.With increasing annealing temperature,some electrochemical properties and kinetic parameters
