Abstract

The invention provides a preparation method of a high-strength and anti-cracking aluminum alloy. The preparation method is applied to the field of alloys. Nb metal is added into an aluminum alloy processing material, the Nb metal has a gas absorption effect, a better effect can be achieved in a subsequent degassing step, the Nb metal, Zr and Cr form synthesis, an excellent composite effect is achieved, and substances in a solution are compounded more stably and are not prone to being bent and cracked after being formed; and V and Bi metals are added, the Bi metal is low in melting point and easy to react to form a solution in the smelting process, but the ductility is too low, the Bi metal and the V metal are complementary in the property of high ductility, the rapid melting effect is achieved, the V metal is high in hardness and stable in chemical formula, the basic stability of the whole solution is improved to a certain degree, and the alloy is not prone to being bent and cracked after being formed.

Description

technical field [0001] The present application relates to the field of alloy technology, in particular to a method for preparing a high-strength, crack-resistant aluminum alloy. Background technique [0002] An alloy based on aluminum with a certain amount of other alloying elements added is one of the light metal materials; in addition to the general characteristics of aluminum, aluminum alloys also have specific characteristics of some alloys due to the different types and quantities of alloying elements added; Good casting performance and plastic processing performance, good electrical conductivity, thermal conductivity, good corrosion resistance and weldability, can be used as structural materials, and has a role in aerospace, aviation, transportation, construction, electromechanical, light and daily necessities Wide range of applications; [0003] During the preparation process of aluminum alloy, it is possible to cause cracks on the surface of aluminum alloy during th...
