摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an asymmetric clad material having excellent shape by solving the serious problem of warpage in the case of manufacturing an asymmetric clad material of titanium and stainless steel, in particular, a thin foil, thereby straightening the warpage in the width direction and the warpage in the longitudinal direction. SOLUTION: In this manufacturing method of the asymmetric clad material comprising at least two kinds of metal layers different in thermal physical property, the clad rolled material of at least two kinds of metal is repeatedly subjected to cold rolling and annealing and finished to a desired thickness. Then, the clad material is passed through a tension leveler in an elongated status within 0.2-1.0% range, and the tension annealing is performed while applying the tension in a range of 5-25% of the tensile strength at the temperature in a range of 50-60% of the minimum melting point of dissimilar metal (the melting point of the metal of the lower melting point if no eutectic compound is formed between the joined metals, while the melting point thereof if the eutectic compound is formed).

摘要： PROBLEM TO BE SOLVED: To provide a copper-based bearing material with a titanium or titanium alloy back plate by a continuous sintering method and a continuous roll pressure-welding method suitable for mass production and manufacturable at a low cost.
SOLUTION: The back plate 3 is formed of Ti or Ti alloy, and an intermediate layer 4 formed of Fe or Fe-Cr alloy is provided between a copper-based bearing layer 2 and the back plate 3. The direct contact of Ti or Ti alloy with metal liable to form an intermetallic compound or with gas is thereby prevented to suppress the formation of the intermetallic compound or a compound with gas. Furthermore, since Fe and Cr used for the intermediate layer 4 are not liable to form an intermetallic compound with Ti at a heat treatment temperature after sintering and pressure welding of a Cu alloy, the copper-based bearing material 1 using Ti or Ti alloy for the back plate 3 can be manufactured without lowering the strength of the copper-based bearing material 1 by the continuous sintering method or the continuous roll pressure-welding method manufacturable at a low cost while allowing sintering and heat treatment.

摘要翻译：要解决的问题：通过连续烧结法和连续辊压焊接方法提供具有钛或钛合金背板的铜基轴承材料，适用于大规模生产并以低成本制造。解决方案：背板3由Ti或Ti合金形成，并且在铜基轴承层2和背板3之间设置由Fe或Fe-Cr合金形成的中间层4。直接接触因此，可以防止易于形成金属间化合物或气体的金属的Ti或Ti合金抑制金属间化合物或气体化合物的形成。此外，由于用于中间层4的Fe和Cr在Cu合金的烧结和压接之后在热处理温度下不易与Ti形成金属间化合物，所以使用Ti或Ti合金的铜基轴承材料1 可以通过连续烧结法或连续辊压焊方法在不降低铜基轴承材料1的强度的情况下以低成本制造背板3，同时允许烧结和热处理。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To perform sheath rolling using a release agent with which strippability which is obtained when using conventional ceramic powder as a release agent is not only secured, but the smoothness of the surface of a rolled product is raised and which is easily removed, in the sheath rolling consisting of applying the release agent on both surfaces of a material to be rolled which is an object of hot rolling, welding it after covering both surfaces and both sides with a dummy material, performing rolling after assembling the sheath and, after that, taking out the rolled product by disassembling the sheath. SOLUTION: A stratiform or fine pulverulent solid lubricant, concretely a dispersed liquid of lubricant which is made by dispersing the powder of mica or talc or fine powder of boron nitride in a liquid medium such as water or alcohol is used as the release agent and the sheath is assembled. Such a rolling method is advantageously applied to even the case that the sheath rolling and clad rolling are performed at the same time.

摘要： PROBLEM TO BE SOLVED: To provide an ultra-sharp cutting tool material in which a hard layer is provided onto the surface of a base material made of steel and which has high corrosion resistance, rigidity, toughness and wear resistance and is capable of high-precision working and can withstand an alkaline corrosive environment, and also to provide its manufacturing method. SOLUTION: An intermediate layer of Ni or Cu is formed by cladding or plating on a base material of the steel which can be hardened to ≥400 HV hardness. Further, a surface layer of Al is formed on the surface layer by cladding. Then, a shape of a cutting tool is formed, and an intermetallic compound of Al and Ni or an intermetallic compound of Al and Cu is formed by carrying out heat treatment for causing diffusion to regulate surface hardness to ≥700 HV. Subsequently, the base metal is heat treated to undergo hardening. The diffusion and the hardening can be performed simultaneously. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a cladding material for a slitting blade having a long service life in which the sharpness of its edge will not be lost during cutting work even if the entire blade is worn out. SOLUTION: This cladding material is formed by using steel with a C content of O.4% or more as a central layer 10, using steel with a C content that is one third to two-thirds of the C content of the central layer 10 as a first outer layer 12, using steel with a C content that is one third to two-thirds of the C content of the central layer 10 as a second outer layer 14, and bonding a stack of these steels together by rolling. The cladding material is subjected to quenching and tempering processes to cause C to be continuously diffused among the layers so as to form a slitting blade having a pyramid-like distribution whose central layer 10 is the hardest.
