摘要： Die Erfindung betrifft eine Vorrichtung (10) und ein Verfahren zur kontinuierlichen Herstellung eines bandförmigen Verbundmaterials (11). Die Seitenränder eines Trägermaterials, das aus Stahl besteht und in einer Transportrichtung kontinuierlich bewegt wird, sind in geeigneter Weise überhöht ausgebildet bzw. werden durch Seitenbegrenzungseinrichtungen (S) in Form von umlaufenden Seitenbändern (19) oder Führungslinealen angestellt, so dass damit eine temporäre formschlüssige Seitenkantenerhöhung an den Seitenrändern (18) des Trägermaterials (16) erreicht wird. Hierbei wird eines aus einem Plattierungswerkstoff bestehenden flüssigen Plattierungsmaterials (P-f) von oben auf eine Oberfläche (17) des bewegten Trägermaterials (16) zwischen den überhöhten Seitenrändern (18h) bzw. den Seitenbegrenzungseinrichtungen (S) aufgebracht, wobei sich durch Erstarren des flüssigen Plattierungsmaterials (P-f) auf dem Trägermaterial (16) ein geschlossener Verbund (21) bildet. Anschließend wird der geschlossene Verbund (21) gebildet aus dem Trägermaterial (16) und dem darauf erstarrten Plattierungsmaterial (P-e) warmgewalzt, so dass damit durch Walzplattieren ein einziges bandförmiges Verbundmaterial (11) bzw. Warmband entsteht, das aus dem Grundwerkstoff und dem Plattierungswerkstoff besteht.

摘要： This cladded aluminum-alloy material is provides with: an aluminum alloy core material, a coating material used to clad both surfaces of the core material; and a brazing material used to clad both of the coating material surfaces, or one of the coating material surfaces which is not at the core material side. The core material, the coating material and brazing filler material have described alloy compositions. The crystal grain size of the coating material before brazing heating is at least 60 µm. In a cross section of the core material in the rolling direction before brazing heating, when R1 (µm) represents the crystal grain size in the plate thickness direction, and R2 (µm) represents the crystal grain size in the rolling direction, R1/R2 is not more than 0.50. As a result, provided is a cladded aluminum-alloy material which exhibits excellent mouldability, and in which the coating material after brazing heating exhibits excellent corrosion resistance.

摘要： [Problem] To provide a heat spreader capable of removing heat from an element more efficiently and immediately than an existing one, and also capable of satisfactorily responding to further enhancement in performance and output of various apparatuses, and a method for efficiently manufacturing the same. [Solution] A heat spreader includes a Cu-Mo layer made of a Cu-Mo composite material and having an average thickness of less than or equal to 0.6 mm and a variation in thickness of less than or equal to 0.1 mm, and a Cu layer directly stacked on each of both surfaces thereof. A method for manufacturing the heat spreader includes planarizing a plate material of the Cu-Mo composite material constituting the Cu-Mo layer, and roll-bonding a Cu plate constituting the Cu layer to each of both surfaces thereof.
