Abstract

The invention relates to a crystal and non-crystal ultrasonic welding method. The method comprises the following steps of: (1) cutting out a 6061 aluminum alloy foil; (2) cutting out a non-crystal alloy Zr44Cu40Ag8Al8 sheet; (3) carrying out welding pre-machining on non-crystal and aluminum alloy surfaces;(4) regulating parameters and welding planes of an ultrasonic metal welding device; and (5) ultrasonically welding the 6061 aluminum alloy foil and the non-crystal alloy Zr44Cu40Ag8Al8 sheet. The invention has the advantages that: (1) the welding of crystals and non-crystals is realized, thus an application space of non-crystals is largely expanded; and (2) the ultrasonic welding of the crystals and the non-crystals is a solid joining technology, is not restrained by metallurgy weldability and does not have the characteristics of air and liquid phase pollution and the like, and a welding joint has high strength and good stability.

Description

technical field [0001] The invention relates to an ultrasonic welding method of amorphous and crystal. Background technique [0002] Amorphous alloys are another structural state of matter relative to crystalline alloys. Its structure is different from crystal materials at the atomic scale, but similar to liquid metals. The atomic arrangement is characterized by long-range disorder, short-range order or macroscopic disorder, without a fixed melting point, and without dislocations, grain boundaries and other common lattice defects in crystal materials. It is precisely because of this unique structure that amorphous alloys exhibit excellent properties in many aspects, such as mechanical properties, corrosion resistance, magnetic properties, etc. The unique properties of amorphous make it widely used in engineering practice. For example, golf clubs developed by utilizing the high strength and high toughness of Zr-based alloys; there is no work hardening effect in amorphous a...
