摘要： A method for making superconductive ceramics laminates comprises forming a thick film (2) of a composite oxide comprising bismuth, strontium, calcium, copper and oxygen on a flat plane of a substrate (1), and orienting and crystallizing the thus formed film by heat treatment to cause the c-axis of composite oxide crystals to be substantially perpendicular to said flat plane of said substrate. An intermediate layer formed of a noble metal, MgO, SrTiO3, yttria-stabilized zirconia or an oxide of a superconductive ceramics-constituting element may be interposed between the film and the substrate.

摘要： PURPOSE: To obtain a Cu alloy with heat resistance and superior electric conductivity by adding a little Y to a Cu-Sn alloy and restricting the oxygen content to a specified amount or below.
CONSTITUTION: Electrolytic copper and electrolytic tin are melted with a high- frequency vacuum melting furnace, and a Cu-10% Y mother alloy is added to refine a Cu-Sn-Y alloy contg. 0.02W0.5wt% Sn, 0.005W0.10wt% Y and ≤0.015wt% oxygen. This molten alloy is cast into an ingot. After planing both sides of the ingot, the ingot is hot rolled and formed into a sheet by repeating cold rolling and annealing. Thus, a Cu alloy with superior electric conductivity and tensile strength fit for fins of a radiator is obtd.

摘要： PROBLEM TO BE SOLVED: To provide a new device and method for plastic forming, because by the conventional plastic forming method, namely ECAP method, shearing force can be applied only once per each forming procedure due to press-fitting of forming material into a die and plastic forming is repeatedly required by changing the direction of the forming material to obtain a distortion-accumulated isotopic crystal, which requires complicated operation. SOLUTION: When plastic forming is carried out by forcibly flowing the forming material 35 in a flow path 34 of a cylindrical container, multiple bends 37, 38 are formed in the flow path to apply shearing force multiple times to the forming material at the bends. Differently from the conventional ECAP method, multiple bends give shearing force multiple times to the forming material by one action of press-fitting of the material and improve efficiency of distortion generation.
摘要翻译：要解决的问题：为了提供一种用于塑性成型的新装置和方法，因为通过常规的塑性成形方法即ECAP方法，由于成形材料压入模具中，每次成型步骤的剪切力只能施加一次通过改变成形材料的方向来重复地需要塑性成形，以获得变形累积的同位素晶体，这需要复杂的操作。解决方案：当通过将成形材料35强制流动在圆柱形容器的流动路径34中进行塑性成形时，在流动路径中形成多个弯曲部37,38，以在弯曲部处对成形材料施加多次剪切力。与传统的ECAP方法不同，多个弯曲通过压配合材料的一个动作对成形材料多次施加剪切力，并提高变形产生的效率。

摘要： PROBLEM TO BE SOLVED: To provide a highly conductive and highly bendable copper alloy wire and a manufacturing method thereof suitably used for a driving cable conductor of robot. SOLUTION: This copper alloy wire comprises a chromium fiberreinforced copper formed or a copper alloy matrix complex material formed in situ. In this case, a wire rod is constituted by forming a chromium layer fiber in copper or a copper alloy matrix in situ. The wire surface is subjected to copper-plating at an intermediate stage of a manufacture step of the wire and the copper plating layer is reformed by applying a plastic processing and then, a heat treatment is applied to the copper in a nonoxidation atmosphere to release a machining distortion. An amount of the chromium layer fiber component is preferably 8-25 wt.%.
