物理场下非晶晶化处理工艺研究
本文作者主要针对热处理工艺、热处理方式、添加元素等因素对非晶材料结构和磁性能进行研究，通过利用热重分析，X射线以及振动样品磁强计对永磁非晶材料的结构和性能进行了研究，以及热处理后对永磁材料的影响。
在研究非晶合金材料的过程中，要观察非晶合金在热处理晶化后与晶化前的组织性能和磁性能的差异，以及晶化后晶粒的均匀性和晶化前的差异，以及在原有非晶合金的基础上添加Nb、Zr、Cu、Mo、Co等元素后对非晶形成能力和非晶的热稳定性的影响。
非晶合金经过晶化处理后，熔点高的元素Nb、Zr、V容易和Fe、B等元素在晶界处形成Nb-Fe-B、Zr(Nb)Fe2和(Nb,V,Zr)-Fe-B等析出相，从而抑制了晶粒的长大；非晶合金在存在Zr、Co等元素的情况下会细化晶粒，提高晶化后合金的组织性能和磁性能。
本文作者在研究热处理对非晶合金处理后不同的添加元素以及处理方法对组织性能产生的影响过程中，研究发现：非晶合金中掺杂不同元素以及热处理方式的不同都会导致组织以及磁性能之间存在很大的差异，因此本文研究热处理方式对非晶合金的材料组织性能转变有影响。

Abstract
In recent years, with the development of science and technology, the study of bonded NdFeB permanent magnet gets more and more. The performance and the application scope of NdFeB permanent material developed rapidly. In order to give full play to Chinese rare earth resources and promoting the development of permanent NdFeB magnetic industry，Our ongoing comprehensive effort。
The authors focused on rapid quenching, heat treatment, and other factors added element on the structure and magnetic nanocomposite permanent amorphous materials can be studied by using thermal analysis,X-rays and vibrating sample magnetometer (VSM) for the structure and properties of amorphous materials permanent magnets have been studied, and the effects of heat treatment after the permanent magnet material.
In the study of amorphous alloy in the process, to observe the differences in organizational performance and magnetic energy of crystallization front, as well as differences in uniformity and crystallization of grain before after crystallization of amorphous alloy crystallization after the heat treatment, and after adding Nb, Zr, Cu, Mo, Co and other elements on the basis of the original amorphous alloy forming ability of amorphous and amorphous thermal stability.
After crystallization of amorphous alloy processing, refractory elements Nb, Zr, V easy and Fe, B and other elements to form precipitates at the grain boundaries with Nb-Fe-B, Zr (Nb) Fe2 and (Nb, V, Zr) -Fe-B, Thereby inhibiting the growth of grains; with Zr, the presence of amorphous alloys Co and other elements of the grain refinement, improved after crystallization and magnetic properties of Alloy.
The author studies the impact of heat treatment on the amorphous alloy treatment process after adding different elements and processing methods of organization on performance, the study found: Amorphous alloys doped with different elements and different heat treatments will lead the organization and the magnetic properties of there is a big difference, so this study of heat treatment on the microstructure and properties of amorphous alloy material changes affecting.
Keywords: amorphous alloy, heat treatment, crystallization process, anisotropy
