Embodiment Construction

[0023] An ultrasonic consolidation forming method of a zirconium-steel layered composite material, comprising the steps of:

[0024] (1) Carry out surface cleaning treatment to the welded surfaces of the zirconium plate (3), the intermediate layer metal foil and the steel plate (1);

[0025] (2) Stack the metal foil of the middle layer on the welding surface of the steel plate (1), and place the steel plate stacked with the metal foil of the middle layer on the ultrasonic consolidation forming workbench, with the metal foil of the middle layer facing up; preheat Heating up, the preheating temperature is 50-250°C;

[0026] (3) Use ultrasonic consolidation forming equipment (2) to travel straight from one end of the plate to the other end in the same direction for welding, so that the weld seam is even. The consolidation pressure during ultrasonic welding is 1200-2500N, and the ultrasonic amplitude is 10-40μm , the consolidation speed is 20-80mm / s; until the middle layer metal ...

Abstract

The invention discloses an ultrasonic consolidation forming method of a zirconium-steel layered composite material, which comprises the following steps: 1) performing surface cleaning treatment on the welding surface of the zirconium plate and the steel plate, 2) stacking the zirconium plate on top and the steel plate on the bottom to form a unit 3) Place the unit body on the ultrasonic consolidation forming workbench, preheat and raise the temperature, 4) Use ultrasonic consolidation forming equipment to weld according to a certain path until the zirconium steel composite forming. The invention belongs to low-temperature manufacturing, zirconium steel is combined by physical metallurgy, the diffusion layer is thin, the production cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to an ultrasonic consolidation forming method of a zirconium-steel layered composite material. [0002] technical background [0003] Zirconium is a rare metal with the advantages of easy processing, good corrosion resistance and low thermal neutron absorption cross-section, especially the corrosion resistance of zirconium is better than stainless steel, titanium, nickel alloy, etc., and it is more and more used in petroleum, Chemical and other industries, but are often limited by the price of zirconium. Zirconium-steel composite plates can replace pure zirconium in the manufacture of pressure vessels, which not only reduces manufacturing costs, but also greatly saves zirconium resources. Therefore, the composite of zirconium and steel is an important technology in engineering, but a very satisfactory method has not been found yet. There are certain difficulties in th...
