摘要： In a method for producing a three-dimensionally shaped object, a powder layer is formed by feeding a powdery material to a substrate and a solidified layer is formed by irradiating a light beam on a specified portion of the powder layer to sinter or melt the specified portion of the powder layer. A three-dimensionally shaped object having a plurality of solidified layers laminated one above another is obtained by repeating the powder layer formation and the solidified layer formation. In the method, a stress is preliminarily applied to the substrate to reduce the amount of deformation of the substrate after production of the shaped object prior to the powder layer forming step.

摘要： A metal powder for use in a metal laser-sintering wherein a three-dimensional shaped object is produced by irradiating a powder layer of the metal powder with a light beam to form a sintered layer and thereby laminating the sintered layers. The metal powder of the present invention is characterized in that it comprises an iron-based powder and at least one kind of powder selected from the group consisting of a nickel powder, a nickel-based alloy powder, a copper powder, a copper-based alloy powder and a graphite powder; and the iron-based powder has been annealed. In such metal powder, the iron-based powder is in a softened state due to the annealing treatment thereof. Accordingly, the use of the metal powder in a metal laser-sintering process makes it possible to reduce a machining resistance attributable to the residual metal powder adherent to the surface of the shaped object, which leads to an achievement of an extended lifetime of a machining tool.

摘要： A method of manufacturing a three-dimensionally shaped object by irradiating a metallic material with light beams, wherein the metallic material is supplied at a high density to increase the density and the strength of the three-dimensionally shaped object. The method of manufacturing a three-dimensionally shaped object comprises: an irradiation step of irradiating a metal mesh (2) formed of metal wires and a powder layer (3) formed of metal powder with light beams (L) to form a solidified layer or molten layer; and a laminating step of repeatedly performing the irradiation step for metal meshes to form a three-dimensionally shaped object. In the method, both of the metal mesh (2) and the metal powder are supplied in combination as the metallic material. Therefore, the method enables to supply the metallic material at a higher density compared to the case where metal powder is supplied alone, and enables to produce a three-dimensionally shaped object with higher dimensional accuracy, higher density and higher strength.

摘要： A cutting tool is provided which includes a steel metal body and a cemented carbide cutting tip secured to the metal body by a metallic layer. The metallic layer has a high-strength metallic portion and a high-toughness metallic portion. The high-strength metallic portion is made of a metal having a thermal expansion rate between a thermal expansion rate of the metal body and the thermal expansion rate of the cutting tip. The high-toughness metallic portion is located between edge portions of a securing region of the metal body and the cutting tip and has toughness larger than that of the high-strength metallic portion. The cutting tool can decrease the possibility of cracks being generated at the edge portions of the securing region by selecting a thermal expansion rate of the metallic layer so as to decrease the thermal stress caused during the cooling process after welding, and further by positioning a high-toughness metallic layer at the edge portions of the securing region where stress is concentrated and positioning a high-strength metallic layer meeting the strength requirement at the remaining portion of the securing region.

摘要： A process of debinding a powder compact formed from a mixture of a sinterable powder and an organic binder utilizes a furnace for heating therein the powder compact at a pressure lower than an atmospheric pressure in order to remove an excess amount of the organic binder. A control is made to vary the furnace pressure and/or a heating rate in accordance with a monitored parameter so as to effectively and successfully removed an excess amount of the organic binder which would cause an unacceptable defect in a finished product. The parameter is selected as indicative of a condition of the furnace or a cracked gas being generated by decomposition of the organic binder, and includes, for example, a furnace temperature, density, volume, or the other measurable characteristics of the cracked gas.
