Description
Technical Field
The invention relates to the field of metal materials and metal material processing, in particular to a high-strength and high-toughness wrought aluminum alloy and a preparation method thereof.
Background
Aluminum and aluminum alloy are known as '21 st century green environment-friendly engineering materials' due to excellent properties of low density, high specific strength, abundant reserves, easy recovery and the like, and have great development prospects in the aspects of realizing light weight of vehicles, light and thin miniaturization of devices, energy conservation, emission reduction, green development and the like. The main design idea of high-strength aluminum alloy at home and abroad for many years is to obtain high-strength aluminum alloy materials by adding rare earth and other alloy elements or by a special preparation process, and various aluminum alloys taking rare earth as main alloy elements or rare earth as trace elements are developed. But the industrial popularization and application progress is slow due to the defects of high material cost or high preparation difficulty and the like. In addition, the ultrahigh-strength aluminum alloy has low ductility and toughness, and the high-efficiency forming and engineering application of important parts are severely restricted.
At present, high-strength and high-toughness wrought aluminum alloys mainly comprise: al-Mg, al-Zn-Mg, al-Mg-Ag and other alloy series. In the field of the development of wrought aluminum alloys, there are three main methods to improve the processing plasticity of aluminum: (1) raising the deformation processing temperature; (2) The size of aluminum crystal grains is reduced through strong deformation, so that the texture is weakened, and the plasticity of the alloy is improved; (3) By adding the alloy elements, the critical shear stress of twin crystals or a sliding system and the like can be changed by causing the change of aluminum crystal lattices through alloying, so that the deformation mode (sliding or twin crystal model) of the alloy is further changed, the texture of the alloy is weakened, and the plasticity of the alloy is increased. During the non-equilibrium solidification process, a large amount of eutectic Mg is precipitated 17 A1 12 The phase is distributed in the crystal boundary of the primary crystal alpha-Al phase in an irregular net shape, and the phase is hard and brittle and has great adverse effect on the mechanical property, particularly the plasticity of the alloy. Therefore, the development of the rare earth-free low-cost high-toughness aluminum alloy has important significance for expanding the application of the aluminum alloy.

Further, in the step (2), pure Al is placed in a crucible, the temperature is raised to 680-760 ℃, the pure Al is completely melted while maintaining the temperature at 680-760 ℃, then pure magnesium, pure antimony and Al-Zn intermediate alloy, al-Zr intermediate alloy, al-Be intermediate alloy, al-Ag intermediate alloy and Al-Cr intermediate alloy are sequentially added, mechanical stirring is carried out for 15 min-30 min at the temperature of 680-760 ℃, then standing is carried out for 15 min-30 min, alloy melt is obtained, and then the alloy melt is made into ingots by adopting a metal mold water-cooling solidification process, so as to obtain casting alloy.

Wherein, the content of Ag in the aluminum alloy is controlled to be 0.5-1.0%, ag is a typical element with precipitation strengthening effect in the aluminum alloy, the solubility maximum value of Ag in the aluminum alloy is 14.8% (561 ℃), the solid solubility of Ag in the aluminum alloy is sharply reduced along with the reduction of temperature, and the solid solubility is only 0.45% at 200 ℃. As the temperature is lowered, ag has high melting point (771.5 ℃) and high-hardness Mg in the aluminum alloy 2 Mg with reasonable size, shape and distribution by precipitation of Ag phase 2 The Ag phase can realize the function of precipitation strengthening, and meanwhile, a proper amount of Ag can refine aluminum alloy grains in the aluminum alloy. By adding small amount of Ag element to form Mg 2 Ag phase separation, allowing Mg to react 17 Al 12 Changing from continuous network to semi-continuous network or broken network to improve Mg 17 Al 12 Phase morphology, thereby improving alloy properties. However, when the Ag content is very low (less than 0.5%), mg is contained in the alloy 2 When the Ag content is less, the effects of grain refinement and precipitation strengthening cannot be achieved. The melting point of the alloy decreases with the increase of the Ag content, when the Ag content is higher (especially more than 1.5 percent), the alloy can cause the coarsening of the aluminum alloy crystal grains, and the alloy extends with the increase of the Ag contentThe rate is reduced, the corrosion resistance of the aluminum alloy is also reduced, and the addition of a larger amount of Ag can result in a higher alloy density (the Ag density is 7.28 g/cm) 3 ) Influence the advantage of light weight of the aluminum alloy, and when the Ag content is higher than 3.2%, mg exists in a liquid state 2 Ag phase is formed, the alloy is solidified to room temperature, and Mg begins to be separated out when the alloy is in a liquid state 2 The Ag phase will be very coarse. Therefore, the Ag content in this system is too high and there will be more coarse Mg 2 Ag phase, which affects the alloy performance, and controls the Ag content in the aluminum alloy to be 0.5-1.0% in order to ensure that alloy elements are dissolved into the matrix as much as possible; in addition, cr can be greatly dissolved in Ag (at 139 ℃, the solid solubility of Cr in Ag can reach 21 percent) to form a beta-Ag phase, and the addition effect of Cr element can be influenced by the existence of a large amount of Ag in the alloy. The Cr content in the aluminum alloy is controlled to be 2-3.2%, and the Cr element is also an element with precipitation strengthening effect in the aluminum alloy. The maximum solubility of the Cr element in aluminum is 8.85%, and the solubility decreases greatly with decreasing temperature, and decreases to 1% or less at 200 ℃. After Cr is added into aluminum alloy, mg with better thermal stability and 823 ℃ of melting point can be formed 3 Cr 2 The granular phase can be used as an alpha-Mg nucleation core to achieve the purpose of refining the matrix phase of the aluminum alloy, so that the strength of the alloy is improved, and good plasticity is kept; cr element can also be added to form net Mg 17 Al 12 The phase transition is open mesh.
