摘要： Disclosed is a method of brazing articles together to form at least one braze defined by complementarily curved faying surfaces on the articles, the faying surfaces each having at least one region of curvature comprising at least one point from which the surface curves in more than one direction, the method comprising the steps of: a) disposing between the complementarily curved faying surfaces at least one amorphous brazing alloy preform of complementary curvature at least in part to said at least one region of the complementarily curved faying surfaces to conform to the complementarily curved faying surfaces in said region; and b) heating the articles and at least one amorphous brazing alloy preform to a brazing temperature at which the amorphous brazing alloy flows and brazes. and brazing alloy preforms for use in such methods. Methods of forming an article comprising a curved surface from a sheet of an amorphous metal alloy are disclosed, by applying heat from a fluid to a sheet of the amorphous metal alloy to raise at least a portion of the sheet to a temperature above the glass transition temperature T g and below the crystallization temperature T x .
摘要翻译：公开了一种将制品钎焊在一起以形成由物品上的互补弯曲的拼接表面限定的至少一个铜焊的方法，所述接合表面各自具有至少一个曲率区域，所述至少一个区域包括至少一个点，所述表面在多于一个方向上从该点弯曲所述方法包括以下步骤：a）至少部分地将互补曲面的至少一个互补曲率的至少一个非晶态钎焊合金预制件设置在所述互补弯曲的引导面之间，以使所述至少一个互补弯曲的引导表面的所述至少一个区域符合互补弯曲的接合所述区域中的表面; 以及b）将所述制品和至少一种无定形钎焊合金预制件加热至非晶态钎焊合金流动并钎焊的钎焊温度。和用于这种方法的合金预成型件的钎焊。公开了从非晶态金属合金的片材形成包含弯曲表面的制品的方法，通过将热量从流体施加到非晶态金属合金的片材上，将片材的至少一部分升高到高于玻璃化转变温度温度Tg并低于结晶温度Tx。
