Abstract

The invention relates to a preparation method and application of aluminum-containing alloy powder. The preparation method utilizes the characteristic that an initial alloy solidification structure contains a matrix phase and a dispersed particle phase, and removes the matrix phase through reaction of an acid solution, so that the dispersed particle phase is separated out, and the aluminum-containing alloy powder is obtained. The preparation method is simple in process, can be used for preparing nano-scale, sub-micron-scale, micron-scale and millimeter-scale aluminum-containing alloy powder with different morphologies, and can be applied to the fields of photoelectronic devices, wave-absorbing materials, catalysts, 3D metal printing, metal injection molding, anticorrosive coatings and the like.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a preparation method and application of aluminum alloy powder and an alloy strip. Background technique [0002] Although there are many methods for preparing alloy powders, each method has certain limitations. For example, the disadvantages of the liquid phase method are low yield, high cost and complicated process. The disadvantage of the mechanical method is that it is difficult to classify after the powder is prepared, and the purity, fineness and shape of the product are difficult to guarantee. Rotating electrode method and gas atomization method are the main methods to prepare high-performance alloy powder at present, but the production efficiency is low and the energy consumption is relatively large. Jet milling and hydrodehydrogenation are suitable for large-scale industrial production, but have strong selectivity to raw material metals and alloys. In addition, ...
