Embodiment Construction

[0027] Step 1: Select the formula of each element and substance according to the table below, and calculate the weight of each substance required based on the total amount of the prepared alloy of 1000kg.

[0028]

[0029] Step 2: First add aluminum ingots or molten aluminum into the melting furnace, heat it to melt it completely and keep it warm at 700-800°C; the melting process is completed in a closed environment;

[0030] Step 3: Add the alloy elements selected in Step 1 according to the proportion of the formula to completely dissolve and melt them, and stir the mixed melt evenly;

[0031] Step 4: Refining the above alloy melt in a furnace; adding a refining agent to the alloy melt and stirring evenly, and the melt refining is operated in a closed environment;

[0032] Step 5: After refining and removing slag, degas the melt with protective gas argon, and at the same time add titanium boron composite modifier (20 mesh) into the alloy melt with protective gas argon in a...

Abstract

The invention discloses a titanium boron compound modified high-performance aluminum alloy material and a preparation method of the high-performance aluminum alloy material; the titanium boron compound modified high-performance aluminum alloy material is characterized in that the alloy comprises the following components in percentage by weight: 3.0-7.0% of Cu, less than or equal to 0.8% of Mn, less than or equal to 1.2% of Mg, less than or equal to 2.3% of Ni, less than or equal to 0.2% of Zn, less than or equal to 0.2% of Ti, less than or equal to 0.25% of Zr and the balance is Al and unavoidable micro-impurity, wherein the titanium boron compound modifier is 1ppm to 0.1%; and the content of the impurity element is less than or equal to 0.05% in single and less than or equal to 0.15% in total. The aluminum alloy provided by invention, compared with normal aluminum alloy has a finer grain structure and higher purity.

Description

technical field [0001] The invention belongs to an aluminum alloy material and a preparation method thereof, in particular to a high-performance aluminum alloy material with titanium-boron composite deterioration and a preparation method thereof. Background technique [0002] Modification can greatly improve the comprehensive mechanical properties and chemical stability indicators of aluminum alloys, sometimes even subversively. Substances that can produce modification are called modifiers. [0003] After adding a small amount of Ti, Zr, and B to the cast aluminum alloy, a fine insoluble intermetallic compound is formed in the alloy, and its particles have nearly the same lattice type and similar lattice constant as Al, or have a coherent lattice. The corresponding crystal planes can be used as the crystallization core of the Al solid solution to refine the grains. [0004] Currently, there are several ways to use Ti and B metamorphism: [0005] 1. Titanium boron flux refi...
