%X The microstructure and magnetic properties of coercive powder prepared by hydrogenation disproportionation desorption recombination method (HDDR) and composed of dual phase Nd2(Fe, Co)14B and Nd2(Fe, Co)17 alloy have been investigated. The decrease in B content in monophase Nd2(Fe, Co)14B alloy induced the formation of Nd2(Fe,Co)17 phase. The remanence Br, of dual alloy Nd12.5 Fe81.5-xCo6Bx with x= 5.2 is higher than that of monophase Nd12.5Fe81.5-xCo6Bx with x=5.88. This may be due to an exchange-coupling interaction between Nd2(Fe, Co)14B and Nd2(Fe, Co)17 phase.
