【摘要】 介绍了采用HDD法制备的各向同性NdFeCoB磁粉，通过真空热轧取向以后，热处理方式和温度对各向异性磁粉磁性能的影响。结果表明，采用700～900℃的双级热处理，使磁性呈降低趋势；而采用单级热处理，可有效改善各向异性磁粉性能。更多还原

【Abstract】 The isotropic NdFeCoB magnetical powders prepared by HDD method be-come anisotropic after hot rolling in vaeuum- The effects of the mode of subsequent heat treatmenton the magnetical properties of anisotropic powders are investigated. Results show that the mag-netical properties of anisotropic powders tend to decrease after two-stage heat treatment at 700～900℃ and could be improved effectively after one-stage heat treatment.更多还原
