specific Embodiment approach 1

[0009] Specific embodiment 1: The 2D70 aluminum alloy spectrum and chemical standard sample preparation method of the present embodiment is carried out according to the following steps: 1. Weigh 2% to 3% of Cu powder and 0.1% to 0.3% of Mn powder by mass percentage , 0.5%~1% Si powder, 1%~1.5% Fe powder, 1%~1.5% Mg powder, 0.1%~0.15% Cr powder, 1%~2% Ni powder, 0.05%~0.1 % of Ti powder, 0.01% to 0.03% of Pb powder, 0.01% to 0.03% of Sn powder, 0.1% to 0.15% of Zr powder and the rest of aluminum powder; 2. Add the raw materials weighed in step 1 to the casting In the furnace, cast at a temperature of 700°C to 760°C, then perform heat treatment at a temperature of 450°C to 510°C, and cool at room temperature for 1 to 20 hours to obtain an ingot; 3. Perform a low-magnification inspection on the ingot obtained in step 2 and uniformity initial inspection; 4. Extrusion molding inspection: Spectral standard sample component uniformity inspection According to the standard sample techn...

specific Embodiment approach 2

[0013] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the Mg powder, Zn powder, Pb powder, Sn powder and Zr powder described in step one can also be selected for use with industrial pure magnesium, industrial pure zinc, Technically pure lead and technically pure tin and zirconium salts. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0014] Embodiment 3: This embodiment differs from Embodiments 1 to 2 in that the casting temperature in step 2 is 720-750°C. Others are the same as the specific embodiment 1 to 2.

Abstract

The invention discloses a preparation method for a 2D70 aluminium alloy spectrum and chemical standard sample, which relates to a developing method of an aluminium alloy standard sample and solves the problem in the prior art that 2-series aluminium alloy standard samples are insufficient. The method comprises the steps of designing components; smelting and casting a circular alloy cast ingot; carrying out homogenizing heat treatment, initial examining for homogeneity and macro examination; carrying out extrusion molding and homogeneity examining; and carrying out valuing and data processing, and then obtaining the 2D70 aluminium alloy spectrum and chemical standard sample. The standard sample developed by the method meets requirements in GB / T15000 Standard Sample Work Guideline and YS / T409 Standard Sample Technical Regulation for Non-Ferrous Metal Product Analysis. The method is suitable for 2D70 aluminium alloy spectrum and chemical analysis.

Description

technical field [0001] The invention relates to a method for developing an aluminum alloy standard sample. Background technique [0002] 2D70 is a supporting product for the military industry. It is mainly used for the production of pre-stretched thick plates. The biggest feature of this product is small stress change and corrosion resistance. It is widely used in the aerospace industry and has a very promising development prospect. At present, there are only 2-series aluminum alloy standard samples in the domestic market, with low Fe and Ni contents, which are not suitable for the use of 2D70 alloys, and the components are relatively small, and do not contain Pb, Sn, Zr and other technical indicators. In recent years, various enterprises have purchased photoelectric direct reading spectrometers and ICP-AES and other instruments from abroad, so that the demand for aluminum alloy spectroscopy and chemical standard samples in my country has increased year by year. In line with...
