    Abstract: The contents of Cr, Fe, Mn, Ti, Si, Cu, N, Al, C, Mg, Mo, B, Zr, and Nb+Ta in a Ni-base alloy weld metal are properly specified and the contents of Co, P, and S in incidental impurities are controlled. In particular, a weld metal having high cracking resistance is formed by specifying the Mn content in a proper range and restricting the contents of B and Zr at low levels. Regarding a Ni-base alloy covered electrode, by specifying the contents of a slag-forming agent, a metal fluoride, and a carbonate serving as flux components in proper ranges and controlling the contents of Mn, Nb+Ta, and Fe in a flux, good welding workability is achieved and a weld metal having good bead appearance is formed.

    Abstract: A nonmagnetic stainless steel which has a higher electrical resistivity than existing nonmagnetic alloys, a production process for producing the stainless steel, and a radio wave receiver. The receiver has a main case and rear cover constituted of a nonmagnetic stainless steel having an electrical resistivity as high as more than 100 ??·cm and consisting of C: not more than 0.1%, Si: 4.0-7.5%, Mn: not more than 2.0%, Ni: 25.5-30.0%, Cr: 15.0-20.0%, Mo: 0.1-3.0%, Cu: 0-2.0%, in mass % and the balance Fe and impurities. Even if some variable magnetic flux generated by a coil of an antenna runs through the main case and the rear cover, the receiving efficiency of the antenna can be prevented from being reduced by eddy current loss and a sufficient radio receiving sensitivity can be obtained. This nonmagnetic stainless steel is produced by hot and/or cold plastic working and subsequent solution treating conducted at 1,000-1,180° C.

    Abstract: 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.
