High-efficiency low-consumption rolled rare earth aluminum alloy and preparation method thereof

Abstract

The invention relates to a high-efficiency low-consumption rolled rare earth aluminum alloy and a preparation method thereof, and belongs to the field of rare earth aluminum alloy manufacturing. The high-efficiency low-consumption rolled rare earth aluminum alloy comprises the following substances of, by mass percentage, 0.8%-2.0% of Mn, 0.3%-0.8% of Er, 0.2%-0.5% of Zr, and the balance Al and impurities. According to the high-efficiency low-consumption rolled rare earth aluminum alloy and the preparation method thereof, common Al and Mn are combined for use, meanwhile, Er and Zr are introduced through a mode that Al-Er intermediate alloy and Al-Zr intermediate alloy are added to serve as raw materials, dynamic recrystallization of an aluminum matrix is strongly stimulated, the rolling deformation capacity of the alloy is remarkably improved, meanwhile, conventional smelting and forming are adopted, homogenization treatment and hot rolling treatment are adopted, the total content of Erand Zr is smaller than 8%, the high-efficiency low-consumption rolled rare earth aluminum alloy and the preparation method thereof have the advantages of being low in production cost, high in production efficiency, easy to operate and the like, and large-scale commercial production is facilitated.

Description

technical field [0001] The invention belongs to the field of rare-earth aluminum alloy manufacturing, in particular to a high-efficiency and low-consumption rolling rare-earth aluminum alloy and a preparation method thereof. Background technique [0002] Due to their unique electron arrangement outside the nucleus, rare earth elements have been widely used in electronics, petrochemical, metallurgy, machinery, energy, light industry, environmental protection, agriculture and other fields. Room temperature and high temperature mechanical properties, enhanced corrosion resistance of alloys and other functions. Therefore, rare earth aluminum alloys have the inherent advantages of aluminum alloys, such as low density, high specific strength, and metallic luster, and at the same time have new characteristics of high heat resistance and excellent creep properties. Although the existing rare-earth aluminum alloys have excellent mechanical properties, they are not conducive to gener...
