    • A method is disclosed for forming a billet (B1-B27) comprising a core body (C, 51, 53, 55, 57, 62, 72) of solid steel housed in a tube (J, 12, 52, 54, 58, 63, 73) of stainless steel, nickel-chrome, nickel-copper and copper-nickel alloys. The billet can be square or round and can be hot rolled in a conventional rolling mill to form a corrosion resistant product (R, F). The tube is fabricated from one or more plates or strips of the alloy. The plates or strips may be pressed or rolled to conform to the shape of the core body against which they are placed and welded together along their abutting edges so that there is an interface (Z) between the plates and the core body. The welds may penetrate into the core body. Briquettes (Ea, Et, Em) of finely divided aluminium, titanium and/or magnesium are placed adjacent the interface in the tube. The tube may be closed to prevent gases outside the billet from penetrating to the interface. Before the tube reaches a temperature at the interface at which oxidation starts, the ends of the billet are heated up causing the briquettes to scavenge oxygen from the residual air at the interface. Alternatively, reliance may be placed on the briquettes to scavenge oxygen from the residual air and also from atmospheric air and furnace gases before they can penetrate to the interface. The briquettes of aluminium or magnesium (Ea, Em) melt before the billet reaches its rolling temperature and a further element (Ea) of finely divided carbon steel may then be inserted between these briquettes and the steel body to prevent the molten metal from penetrating to the interface. In an open tube, an additional element (Eu) composed of ammonium chloride or urea may be inserted between the carbon steel briquette and steel body. The additional element disassociates at a low temperature to scour residual gases out of the interface. The elements can be placed directly in the tube or in a cartridge (20,30) which is subsequently welded to the tube.
    • 公开了一种用于形成坯料(B1-B27)的方法,所述坯料(B1-B27)包括容纳在管(J,12,52,54,58,62,72)中的固体钢的芯体(C,51,53,55,57,62,72) 63,73)不锈钢,镍铬,镍铜和铜镍合金。 坯料可以是方形或圆形,并且可以在常规轧机中热轧,以形成耐腐蚀产品(R,F)。 管由一个或多个合金板或条制成。 板或条可以被压制或滚动以符合它们被放置的芯体的形状并沿其邻接边缘焊接在一起,使得在板和芯体之间存在界面(Z)。 焊缝可能渗透到芯体中。 精细分散的铝,钛和/或镁的压块(Ea,Et,Em)放置在管中的界面附近。 管可以封闭,以防止坯料外部的气体渗透到界面。 在管达到氧化开始界面处的温度之前,坯料的端部被加热,使得团块从界面处的残余空气中清除氧气。 或者,可以依赖于团块来清除残留空气中的氧气,还可以从大气和炉气中清除氧气,然后才能渗入界面。 铝或镁(Ea,Em)的团块在坯料达到其轧制温度之前熔化,然后可以将另外的细分碳素元素(Ea)插入这些团块和钢体之间,以防止熔融金属渗入 界面。 在开管中,可以在碳钢团块和钢体之间插入由氯化铵或尿素组成的附加元素(Eu)。 附加元件在低温下分解,从而将残留气体冲洗出界面。 这些元件可以直接放置在管中或者随后焊接到管的盒(20,30)中。

    • A billet [B1-B23] is provided comprising a body [C, 1 10, 110a, 122, 62] of solid steel and a cladding [J] of an alloy comprising stainless steel, nickel-chrome, nickel-copper and copper-nickel alloys. The cladding may be comprised of a square tube in which the body is inserted with an interface [Z] at which the cladding becomes bonded to the body when the billet is heated and rolled or otherwise worked into a ferrous product [F, R, 120, 123]. At least one element [Ea, Et, Em] composed of a mass of finely divided scavenging aluminium, titanium or magnesium, is placed in the tube adjacent the body and separate from the interface. The elements are advantageously compressed into briquettes which scavenge oxygen from residual air at the interface to prevent oxidation of the cladding at the interface. The tube may be closed to prevent gases outside the billet from penetrating to the interface. Alternatively, reliance may be placed on the briquettes to scavenge oxygen from the residual air and also from atmospheric air and furnace gases before they can penetrate to the interface. The ends of the billet are heated up before the tube reaches a temperature at the interface at which oxidation starts. The briquettes of aluminium or magnesium [Ea, Em] melt before the billet reaches its rolling temperature and a further element [Ea] of finely divided carbon steel may then be inserted between these briquettes and the steel body to prevent the molten metal from penetrating to the interface. In an open tube, an additional element [Eu] composed of ammonium chloride or urea may be inserted between the carbon steel briquette and steel body. The additional element disassociates at a low temperature to scour residual gases out of the interface. The elements can be placed directly in the tube or in a cartridge [60-60g] which is subsequently welded to the tube.

    • Disclosed is an elongate element, especially a cylindrical semifinished product such as a wire, rod, or similar, comprising a metal core as the predominant basic material and a coating that concentrically surrounds said basic material. The metal core (1) is made of an inexpensive, light metal that is easy to process, e.g. aluminum, while the outer, thinner coating represents an envelope (2) which is made of a harder, less conductive, and thus less corrosive metal, e.g. titanium, and overall ensures a substantial qualitative improvement of the finished product while altogether forming a sandwich material or a semifinished product having a concentric structure. The coating is applied galvanically or by means of thermal spraying, vaporizing, or plating with a film strip. The inventive elongate element can be used for producing rivets, screws, and pins in aircraft construction.
