    摘要: Glass or ceramic-to-metal composites or seals wherein the glass or ceramic is bonded to an iron base alloy consisting essentially of from 1-5% silicon and from 1-10% chromium, remainder iron. The alloy develops a thermal oxide film which consists essentially of chromium oxide and .alpha.Fe.sub.2 O.sub.3 which may comprise from 10 to 100% of the oxide film thickness on the metal. The invention also includes a process of bonding the glass or ceramic to the metal which eliminates the need of a prolonged heat treatment performed in a special atmosphere.

    摘要: A method for producing a semi-finished metal product (2), in particular a semi-finished copper product, for a metal-copper substrate, in particular for a copper-ceramic substrate, including:



    providing a first metal layer (11), in particular a first copper layer, and a second metal layer (12), in particular a second copper layer,
    joining the first metal layer (11) and the second metal layer (12) to form the semi-finished metal product (2), wherein, chronologically before the first metal layer (11) is joined to the second metal layer (12) by means of different temperature treatments, a grain growth in the first metal layer (11) and/or the second metal layer (12) is initiated in such a way that in the produced semi-finished metal product (2), in particular in the produced metal-copper substrate, a first grain size in the first metal layer (11) differs from a second grain size in the second metal layer (12).
