Abstract

The invention relates to a novel antirust aluminium alloy material. The aluminium alloy material comprises the following raw materials: Si, Fe, Cu, Mn, Mg, Zn, Zr, Be and Al. The novel antirust aluminium alloy material has the beneficial effects that the content of Zr in the novel antirust aluminium alloy material is moderate, so that the strength and plasticity of base materials and weld joints are obviously improved and the weldability is enhanced; meanwhile, Zr and Al form a ZrAl3 compound, so that a recrystallization process can be hindered and recrystallized grains can be refined; and by adding a small quantity of Zn to the novel antirust aluminium alloy material, the strength of the base materials and the weld joints can be effectively improved via the dispersion strengthening effects of the precipitated MgZn2 phase and Al2Zn3Mg3 phase, and the corrosion resistance of the base materials and the weld joints is optimal. Therefore, the novel aluminium alloy material has high mechanical strength and strong corrosion resistance and weldability, and solves the problem of gaps in the materials of large-scale all aluminium alloy high-speed ships (hovercrafts) in China.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a novel antirust aluminum alloy material. Background technique [0002] At present, my country's anti-rust aluminum alloy is 5××× series A1. Mg alloy, 5××× belongs to the more mature and commonly used aluminum alloy series. There are as many as 28 types of 5-series aluminum alloy grades in my country (see GB 9048-2008 "Chemical Composition of Deformed Aluminum and Aluminum Alloys"), the main alloying element is magnesium, and the mass fraction of magnesium is between 3-5%, so it can also be called For aluminum magnesium alloy. The main characteristics of aluminum-magnesium alloys are low density, high tensile strength and elongation. Mechanical properties of 5××× aluminum-magnesium alloy: tensile strength σb (MPa) ≥ 270, yield strength σ0.2 (MPa) ≥ 120. [0003] The most representative of the 5××× aluminum-magnesium alloys is 5083. At present, the above-mentioned aluminum-magnes...
