研究了Pr60Al10Ni10Cu20大块金属玻璃的结构和磁性随Fe含量的变化关系,结果表明Pr基合金逐步从玻璃状态,转变为非晶与纳米晶的复合状态,最后成为纳米晶合金,Pr基合金的磁性也相应地发生变化.提出了一种通过对大块稀土基金属玻璃进行Fe掺杂,制备出微观结构和性能具有可调控性的大块纳米晶合金的方法,并讨论了纳米晶结构和性能的关系.
The relationship between the structure and magnetic properties of Pr60Al10Ni10Cu20 bulk metallic glass with the content of Fe was studied. The results show that the Pr-based alloy gradually changes from the glass state to the composite state of amorphous and nanocrystalline, and finally becomes the nanocrystalline alloy. Also correspondingly changed.A method for preparing large-sized nanocrystalline alloy with controlled microstructure and properties by Fe doping of bulk rare earth-based metallic glass was proposed, and the nanocrystalline structure and properties Relationship.
