摘要： The present invention addresses the problem of providing a sintered magnet production method in which the cracking of the sintered magnets hardly occurs. It is a method having a pulverizing process in which a lump of alloy of a material for a sintered magnet is pulverized by a method including a hydrogen pulverization method, a filling process in which a cavity is filled with alloy powder obtained by the pulverizing process, an orienting process in which the alloy powder is magnetically oriented by applying a magnetic field to the alloy powder, and a sintering process in which the alloy powder is sintered by heating it according to a predetermined temperature history. In the sintering process, the alloy powder is heated in an inert-gas atmosphere at a higher pressure than atmospheric pressure until the temperature reaches a predetermined pressurization maintenance temperature which is higher than a hydrogen desorption temperature as well as equal to or lower than the sintering temperature. By performing the heating treatment in such a pressurized inert gas, hydrogen-gas molecules remaining in the alloy powder are prevented from suddenly desorbing from the alloy powder, so that the cracking of the sintered magnets hardly occurs.

摘要翻译： 本发明的目的在于提供一种不易发生烧结磁体的破裂的烧结磁体制造方法的问题。 作为粉碎工序的方法，其中通过包括氢粉碎法的方法将用于烧结磁体的材料的合金块粉碎，其中通过粉碎过程获得的合金粉末填充空腔的填充工艺， 通过向合金粉末施加磁场而使合金粉末磁性取向的定向方法，以及根据规定的温度历史将合金粉末进行加热烧结的烧结工序。 在烧结过程中，合金粉末在比大气压更高的惰性气体气氛中加热直到温度达到高于氢解吸温度的预定加压维持温度，并且等于或低于烧结 温度。 通过在这种加压惰性气体中进行加热处理，可以防止残留在合金粉末中的氢气分子从合金粉末中突然解吸，从而几乎不发生烧结磁体的破裂。

摘要： The present invention addresses the problem of providing a sintered magnet production system using a press-less method capable of minimizing the distortion of a sintered magnet. It is a system including: a filling device 11 for filling a cavity 211 of a container 21 with alloy powder of a material for a sintered magnet; an orienting section 13 for orienting the alloy powder held in the cavity 211 by applying a magnetic field without applying a mechanical pressure to the alloy powder; and a sintering section 15 for sintering the alloy powder oriented by the orienting section 13, by heating the alloy powder without applying a mechanical pressure to the alloy powder. The orienting section includes: an air-core coil 131; and two ferromagnetic members 132 made of a ferromagnetic material to be arranged within the air-core coil 131 at respective open ends of the air-core coil 131 with a space for containing the container 21 in between. The ferromagnetic members 132 adjust the magnetic field within the air-core coil 131 toward a direction parallel to the axis of the air-core coil 131, whereby the distortion of a sintered magnet is minimized.
