Abstract: The invention relates to a method for producing a steel shaped body, particularly, for example, a component for common rail fuel injection valves, comprising the method steps of: forming a powderous composition based on iron oxide, from oxide particles, with the addition of carbon and micro-alloy elements so as to adjust a bainitic microstructure; heating the powderous composition to a sinter temperature; reducing the shaped body obtained by sintering; and cooling the sintered shaped body to room temperature. As a result, from the three essential state phases in a state diagram (10), specifically the ferrite-perlite state range (11), the bainite state range (12) and the martensite state range (13), preferably the bainitic state phase is formed in a medium temperature range by the ferrite-perlite state range (11) being shifted to longer cooling periods and the martensite state range (13) being shifted to lower temperatures.

Abstract: 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, filling process wherein a cavity is filled with alloy powder obtained by pulverizing process, an orienting process wherein alloy powder is magnetically oriented by applying magnetic field to alloy powder, and sintering process wherein alloy powder is sintered by heating it according to predetermined temperature history. In the sintering process, alloy powder is heated in inert-gas atmosphere at higher pressure than atmospheric pressure until temperature reaches predetermined pressurization maintenance temperature which is higher than hydrogen desorption temperature and equal to or lower than sintering temperature. By performing the heating treatment in a pressurized inert gas, hydrogen-gas molecules remaining in the alloy powder are prevented from suddenly desorbing from alloy powder, so that the cracking of the sintered magnets hardly occurs.

Abstract: An interconnector for a solid oxide fuel cell is manufactured by single-press compacting a powder blend to form a green interconnector with a desired shape of a final interconnector. The powder blend includes chromium and iron, and may include an organic lubricant. At least 50 wt % or more of an iron portion of the powder blend comprises iron particles smaller than 45 um. The green interconnector is then sintered and oxidized to form the final interconnector. The oxidation step occurs in a continuous flow furnace in which a controlled atmosphere (e.g., humidified air) is fed into the furnace in the travel direction of the interconnector. The final interconnector comprises at least 90 wt % chromium, at least 3 wt % iron, and less than 0.2 wt % nitrogen. An average density within a flow field of the final interconnector may be less than 6.75 g/cc.
