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.
摘要翻译：提供了一种切削工具，其包括钢金属体和通过金属层固定到金属体的硬质合金切削刀头。金属层具有高强度金属部分和高韧性金属部分。高强度金属部由具有金属体的热膨胀率与切削刃的热膨胀率之间的热膨胀率的金属制成。高韧性金属部分位于金属体的固定区域和切割尖端的边缘部分之间，其韧性大于高强度金属部分的韧性。切削工具可以通过选择金属层的热膨胀率来减少在固定区域的边缘部分产生裂纹的可能性，从而降低在焊接之后的冷却过程中产生的热应力，并且进一步通过定位高在紧固应力集中的固定区域的边缘部分设置柔性金属层，并且在固定区域的其余部分定位满足强度要求的高强度金属层。

摘要： An object of the present invention is to easily eliminate fumes inside a chamber, so as to improve a positional accuracy of irradiation with a light beam and a machining accuracy in a method for manufacturing a three-dimensional shaped object. A stacked-layers forming device 1 includes a powder layer forming unit 3, a light beam irradiating unit 4, a base 22 which is fixed and on which a powder layer 32 is formed, a lifting/lowering frame 34 which surrounds the circumference of the base 22 and is freely capable of being lifted and lowered, a cover frame 36 which has a window 36a allowing transmission of light beam in its top surface, and whose bottom surface is opened, and which is disposed on the lifting/lowering frame 34 to form a chamber C, and a gas tank 71 for supplying an ambient gas. The lifting/lowering frame 34 is lowered to reduce the volume of the chamber C, so as to discharge fumes generated inside the cover frame 36, which performs replacement with the ambient gas. Since the volume of the chamber C is reduced, it is possible to easily eliminate the fumes, which makes it possible to improve the positional accuracy of irradiation with the light beam L, and the machining accuracy.

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： 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.
