Abstract

The invention relates to a novel antirust aluminum alloy material. The raw materials of the aluminum alloy material include Si, Fe, Cu, Mn, Mg, Zn, Zr, Be and Al; Zr in the novel antirust aluminum alloy material of the present invention The content is moderate, which significantly improves the strength and plasticity of the base metal and the weld, and enhances the weldability. At the same time, Zr and Al form a ZrAl3 compound, which can hinder the recrystallization process and refine the recrystallization grains; the new antirust aluminum alloy Adding a small amount of Zn to the material, the dispersion strengthening effect of the precipitated MgZn2 phase and Al2Zn3Mg3 phase can effectively improve the strength of the base metal and the weld, and make it the best corrosion resistance. Therefore, the novel aluminum alloy material of the present invention has high mechanical strength, corrosion resistance, and strong weldability, and solves the blank problem of materials for large-scale all-aluminum alloy high-speed ships (hovercrafts) in my country.

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...
