Embodiment Construction

[0017]

[0018] It is composed of industrial pure Al, industrial pure Mg and Al-Si, Al-Sb, Al-Zr master alloys. The sample preparation process is as follows. First, Al-RE master alloy is prepared, and graphite crucible is used for melting in a well-type electric furnace. The melting temperature is controlled at 780°C. After the aluminum is melted, add the mixed rare earth wrapped in aluminum thinly at 740°C, and fully stir. After holding the heat for 2 hours, remove the slag and cast. Secondly, after calculation, the experimental alloy samples with different mixed rare earth additions were prepared in batches, and the graphite crucible was also used for melting in the well-type electric furnace. The melting temperature was controlled at 780°C, and the magnesium block was pressed into the bell jar at 680-700°C. After fully stirring, add Al-Si, Al-Sb, Al-Zr intermediate alloys at 740°C after removing slag, add C2Cl6 refining agent to purify the melt after it is fully melted, ...

Abstract

The invention discloses a novel ZL305 (AlMg8Zn) alloy containing rare earth Sb and Zr. The novel ZL305 (AlMg8Zn) alloy containing rare earth Sb and Zr is characterized by comprising, by weight, 8% of Mg, 1% of Zn, 0.1-0.3% of Sb, 0.1-0.3% of Zr and the rest of Al.

Description

technical field [0001] The invention relates to a novel ZL305 (AlMg8Zn) alloy containing rare earth Sb and Zr. Background technique [0002] Aluminum alloy is a relatively young metal material, which only began to be used industrially in the early 20th century. During World War II, aluminum was mainly used in the manufacture of military aircraft. After the war, due to the sharp decrease in the demand for aluminum in the military industry, the aluminum industry began to develop civilian aluminum alloys, expanding its application scope from the aviation industry to the construction industry, container packaging industry, transportation industry, electric power and electronics industry, Various sectors of the national economy such as machinery manufacturing and petrochemicals are applied to people's daily lives. At present, aluminum is used in a large amount and in a wide range, second only to steel, and has become the second largest metal material. [0003] 1. High-strength...
