Microstructure Evolution of Nd in Spray Deposited Magnesium Alloy

摘要：

　　Nd can obviously improve the mechanical properties of spray deposited 1%Nd,2%Nd extruded and heat treatment alloy.Nd solid solution in α-Mg matrix lead to the hardness of 2%Nd spray deposited magnesium alloy extruded is higher than that of after heat treatment.A large number of Al2Nd particles precipitation is the key factor to the highest hardness value(139.4Hv) in 2%Nd magnesium alloy after 370℃/3h+205℃/24h heat treatment.Moreover,the precipitation of Al2Nd accompany with Al2Ca and Al-Mn phase increased.
