摘要： A mold includes a pair of first mold parts, a pair of second mold parts, and a pair of third mold parts that define six surfaces of a molded body substantially having a rectangular parallelepiped shape. At least one of the pair of third mold parts includes an upper mold part and a lower mold part. The upper mold part defines an upper space of a molding space, and the lower mold part defines a lower space of the molding space. The upper mold part and the lower mold part are individually slidable. The lower mold part protrudes toward the molding space with respect to the upper mold part so that a step portion is formed. The upper mold part is slidable in cooperation with the lower mold part in a state in which the step portion is formed or absent.

摘要： A superconducting wire comprises a MgB2 filament, a base material, a high-thermal expansion metal, and a stabilizing material. The high-thermal expansion metal is a metal (for example, stainless steel) having a higher thermal expansion coefficient at room temperature than the MgB2 and the base material (for example, iron or niobium). The manufacturing method includes a step of packing a mixed powder in a first metal pipe, a step of performing wire-drawing on the first metal pipe formed of the metal to be the base material, a step of producing a composite wire by accommodating the first metal pipe in a second metal pipe formed of the high-thermal expansion metal and the stabilizing material, a step of performing wire-drawing on the composite wire, and a step of performing heat treatment.

摘要： A compound roll includes a sintered inner core of a first cemented carbide and at least one sintered outer sleeve of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface, wherein when the inner core and outer sleeve are assembled each joining surface contact to form a bonding interface therebetween. When the assembled, sintered inner core and outer sleeve are heated to a predetermined temperature the sintered inner core and outer sleeve are fused together at the bonding interface to form the unitary compound roll. To reduce the overall cost of the compound roll, a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to an outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll.
