20160097110 | METHOD FOR MANUFACTURING RARE-EARTH MAGNETS - Provided is a method for manufacturing a rare-earth magnet capable of manufacturing a rare-earth magnet having excellent magnetic characteristics from magnetic powder that is prepared by liquid rapid-quenching and including both of nano-crystalline substance and amorphous substance as well. A method for manufacturing a rare-earth magnet includes: a first step of rapidly quenching of molten metal that is represented by a composition formula of (R1) | 04-07-2016 |
20160104572 | METHOD FOR MANUFACTURING RARE-EARTH MAGNETS - Provided is a method for manufacturing a rare-earth magnet capable of preventing the lubricant from flowing down during hot deformation processing, whereby friction force can be made as uniform as possible at the overall region of the sintered body, and so the rare-earth magnet manufactured can have less distribution of magnetic performance. A method for manufacturing a rare-earth magnet includes: a first step of sintering magnetic powder MF as a material of the rare-earth magnet to prepare a sintered body S; and a second step of placing the sintered body S in a cavity K of a forming die M made up of a die D and a lower punch P and/or an upper punch P sliding in the die D, and performing hot deformation processing of the sintered body S to give magnetic anisotropy to the sintered body to manufacture the rare-earth magnet C. In the second step, a lubrication sheet | 04-14-2016 |

20160184895 | METHOD OF FABRICATING A STEEL PART BY POWDER METALLURGY, AND RESULTING STEEL PART - A method for manufacturing by powder metallurgy a steel part is provided. A pre-alloyed powder is prepared, having the desired composition for said part, except for the O and N contents and optionally C contents, with O and N contents of at most 200 ppm, and with an Mn content from 0.4 to 2% by weight and a Cr content of less than or equal to 3%; the powder is placed in a container for which the walls define a space, the shape of which corresponds to that of the part, a getter being at the periphery of the powder, said getter has the capability at a high temperature of absorbing and reducing CO and absorbing nitrogen, and a vacuum is applied and the container is then sealed; the container and the powder are brought to a temperature causing sintering of the powder and densification of said powder not exceeding 5%, evolvement of nitrogen and CO from the powder and their absorption by the getter; densification of said powder is achieved by hot isostatic compaction in order to obtain said part; said part is separated from the container and from the getter; and peeling, heat treatment and machining of said part are achieved. The thereby produced steel part is also provided. | 06-30-2016 |
20160186311 | METHODS OF FORMING MOLYBDENUM SPUTTERING TARGETS - In various embodiments, sputtering targets are formed by introducing molybdenum powder into a sheet bar mold, pressing the powder to form a sheet bar, sintering the sheet bar to form an ingot having a density of at least 90% of a theoretical density, preheating the ingot, rolling the ingot to form a plate, and heat treating the plate. | 06-30-2016 |
