摘　　要：结合国内烧结Nd-Fe-B磁体工业生产过程,研究了相同Nd-Fe-B粉末压制成型后,不同的烧结、回火热处理温度对产品磁性能及退磁曲线方形度的影响。试验结果表明,烧结温度的高低对产品的剩磁、磁能积影响较大;在烧结温度一定后,不同的回火热处理温度对产品性能以及退磁曲线方形度也有一定对应关系。Combing with the industrial production of sintered Nd-Fe-B magnet in China, the effects of different sintering temperatures and tempering heat treatment temperatures on the product magnetic property and demagnetization curve square degree after pressure molding of the same Nd-Fe-B powder were studied. The test results revealed that the sintering temperature had a great effect on remanence and magnetic energy product. After determination of the sintering temperature, different tempering heat treatment temperatures had corresponding relations to the product property and demagnetization curve square degree.
