摘要: Abstract Elements Cu and Nb were added into the sintered Nd–Fe–Co–B magnet in order to improve mechanical properties of magnet. The bending strength increased at low level (⩽1 at%) or additions while fracture toughness slightly for decreased addition. mode was still brittle failure. microstructures these magnets investigated with emphasis on relationship between microstructure using optical microscopy, SEM EDX. New phases found magnets. reason why improved is also discussed.
