| titleOfInvention | Nd (Nd)2Fe14Preparation method and application of B/Al composite material |
| abstract | The invention belongs to the technical field of composite material preparation, and particularly relates to an Nd material 2 Fe 14 A preparation method and application of a B/Al composite material. The Nd is prepared by adopting a flash sintering method 2 Fe 14 The method for preparing the B/Al composite material comprises the following steps: firstly, uniformly mixing aluminum powder and neodymium iron boron powder according to a ratio, adding ethanol, carrying out wet grinding in a ball mill, and carrying out vacuum drying on the powder after the wet grinding; pressing and molding the obtained mixed fine powder by using cold isostatic pressing to obtain a compact composite material billet; placing in a vacuum flash furnace, connecting in series to a circuit, sintering, and applying an electric field during the flash sintering process to obtain Nd 2 Fe 14 B/Al composite material; magnetizing in magnetizing machine to prepare magnetic Nd 2 Fe 14 B/Al composite material. Magnetic Nd of the invention 2 Fe 14 The B/Al composite material has uniform structure and stable structure, and has stronger fracture toughness, compressive strength and better magnetic property. The preparation process disclosed by the invention is simple in process, high in controllability, rapid in flash sintering and short in preparation period, and is expected to be used in production. |
