  1. The microwave magnetic sintering can not only lower the sintering temperature and shorten the sintering time, but also decrease the micro - grain size of magnets and make intergranular phase and grain boundary of main phase distributed well. the abnormal grain growth was found in conventional sintered ndfeb magnets, which may be due to the greater particle size and uneven distribution of powder, and higher sintering temperature and longer sintering time. of course, the abnormal grain growth would deteriorate the magnetic properties

    微波磁場燒結的不但降低燒結溫度,縮短燒結時間,而且使磁體整體加熱,受熱更均勻,因而磁體晶粒更細小,並且主相晶粒邊界趨于規則化,晶間相的分佈更均勻;在常規燒結的磁體中則出現了晶粒異常長大現象,造成這一現象的原因,一方面可能是燒結溫度過高或燒結時間過長,另一方面可能是磨製的粉體均勻性較差,存在的大顆粒被許多細小顆粒包圍,在燒結過程中,大顆粒不斷吞併小顆粒,逐漸長大,而異常長大的晶粒自然會導致磁體性能的惡化。
  2. Measures should be taken to prevent uneven distribution of grain size in diamond blending

    採取措施防止金剛石微粉在投料時出現粒度偏析。
