非晶合金中摻雜不同元素以及熱處理方式的不同都會導致組織以及磁性能之間存在很大的差異,因此本文研究熱處理方式對非晶合金的材料組織性能轉變有影響

摘要在最近幾年,隨著科學和技術的發展,粘結釹鐵硼永久磁鐵的研究變得越來越多。NdFeB永久材料的應用范圍迅速發展。為了充分發揮中國稀土資源,促進永磁釹鐵硼產業的發展,我國正在進行全面的努力。 34626
   本文作者主要針對熱處理工藝、熱處理方式、添加元素等因素對非晶材料結構和磁性能進行研究,通過利用熱重分析,X射線以及振動樣品磁強計對永磁非晶材料的結構和性能進行了研究,以及熱處理后對永磁材料的影響。
  在研究非晶合金材料的過程中,要觀察非晶合金在熱處理晶化后與晶化前的組織性能和磁性能的差異,以及晶化后晶粒的均勻性和晶化前的差異,以及在原有非晶合金的基礎上添加Nb、Zr、Cu、Mo、Co等元素后對非晶形成能力和非晶的熱穩定性的影響。
  非晶合金經過晶化處理后,熔點高的元素Nb、Zr、V容易和Fe、B等元素在晶界處形成Nb-Fe-B、Zr(Nb)Fe2和(Nb,V,Zr)-Fe-B等析出相,從而抑制了晶粒的長大;非晶合金在存在Zr、Co等元素的情況下會細化晶粒,提高晶化后合金的組織性能和磁性能。
  本文作者在研究熱處理對非晶合金處理后不同的添加元素以及處理方法對組織性能產生的影響過程中,研究發現:非晶合金中摻雜不同元素以及熱處理方式的不同都會導致組織以及磁性能之間存在很大的差異,因此本文研究熱處理方式對非晶合金的材料組織性能轉變有影響。

  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.
