Pr基大块纳米晶合金及其特性研究
Pr-based bulk nanocrystalline alloy and its properties
【摘要】 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.
【Abstract】 The formation of bulk nanocrystalline alloys based on the Pr-~60 Al-~10 Ni-~10 Cu-~20 bulk metallic glass forming alloy by doping Fe is reported. By varying the content of Fe, the microstructure of the Pr-based alloy changes progressively from full glassy state to composite with nanocrystalline particles embedded in the glassy matrix, and finally into nano-structured state accompanied by the gradual magnetic property changes. A simple approach to obtain the bulk nanocrystalline material with controllable microstructure is presented, and the relation between microstructure and property is discussed.
