摘要: Abstract The effect of Co on the thermal stability and impact toughness sintered Nd–Fe–B magnets has been investigated. results showed that addition decreased intrinsic coercivity temperature coefficient remanence (α), increased (β) for magnets. with first decreases, reaches a minimum, then starts to increase. possible reasons increasing coefficients were analyzed, relations between microstructure studied.
