摘要:
    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 ascast alloy and alloy annealed at 1 123 K are compose of LaNi5,(La,Mg)2Ni7 and a small amount of LaNi2 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
