Effect of Dy additive on microstructure and magnetic properties of rapidly solidified Nd-Fe-B strips
添加Dy元素对钕铁硼速凝片微观组织和磁特性的影响

Sintered Nd-Fe-B magnets made from strip cast alloys have been studied extensively owing to their strong permanent magnetic properties.Up to now the studies mainly focus on technology parameters of strip casting,including casting temperature,wheel speed and phase transition temperature and so on.However,microstructure and properties of rapidly solidified strips could be influenced by the composition of alloy.In this work,the effects of added Dy element on microstructures and properties of Nd-Fe-B rapidly so...
