Problems solved by technology

British MBH company has spectral standard samples similar to cast aluminum, but the chemical composition range of silicon is unreasonable
The American National Bureau of Standards NIST standard sample system has A356 single-point chemical and single-point spectral standard samples, but the silicon and iron components are high, and the single point cannot be serialized
[0003] At present, the common problems of aluminum alloy standard samples at home and abroad are: few types of chemical elements, large differences in composition uniformity and stability, the main reason for these problems is that the preparation process is not well controlled

Embodiment 1

[0034] The aluminum alloy standard sample that the present invention needs to prepare is to contain the following chemical elements in pure aluminum: Si, Fe, Cu, Mg, Mn, Zn, Sn, Pb, Ni, Ti, Cr, Sr, Ca, V, Ga, Zr , Cd, Be, B and P, the weight percent of each element is as follows: Si: 7.22, Fe: 0.214, Cu: 0.051, Mg: 0.288, Mn: 0.121, Zn: 0.090, Sn: 0.084, Pb: 0.044, Ni: 0.045, Ti: 0.043, Cr: 0.019, Sr: 0.016, Ca: 0.0006, V: 0.032, Ga: 0.059, Zr: 0.0060, Cd: 0.0061, Be: 0.010, B: 0.0006, P: 0.0062.

[0035] Follow the steps below to prepare:

[0036] 1) Batching: Select pure aluminum and intermediate alloys as furnace materials. When batching, the burning loss and volatilization of elements should be considered. For the intermediate alloys, the content of main elements and impurity elements should be accurately grasped.

[0037] 2) Smelting: Melt in a 500kg intermediate frequency furnace first, and then transfer to a holding furnace for standing. The addition method of each ch...

Abstract

The invention relates to a method for preparing a standard multi-element aluminum alloy sample. The method comprises the steps of proportioning materials, melting, casting, homogenization processing, extruding and post-processing, and is characterized in that the standard sample contains the following 20 chemical elements in pure aluminum: Si, Fe, Cu, Mg, Mn, Zn, Sn, Pb, Ni, Ti, Cr, Sr, Ca, V, Ga, Zr, Cd, Be, B and P. The standard sample is manufactured sequentially through proportioning materials, melting, casting, homogenization processing, extruding and post-processing, and finally, standard samples are prepared according to the requirements for the standard samples. By adopting the preparation method, the multi-element aluminum alloy sample with uniform composition and good stability can be obtained.

Description

technical field [0001] The invention relates to a preparation method of a multi-element aluminum alloy standard sample, which is used for preparing the multi-element aluminum alloy standard sample. Background technique [0002] In recent years, automobile lightweight has attracted more and more attention. Aluminum alloy material is the material of choice to realize the lightweight of automobiles. With the rapid development of science and technology, new aluminum alloy products are constantly being developed and put into the market, and some new materials have added trace elements. With the continuous improvement of people's quality requirements, aluminum alloy production enterprises and downstream customers have put forward higher requirements for the analysis of aluminum alloy elements, especially the analysis of trace elements is particularly urgent. At present, the existing standard samples of multi-element aluminum alloys are generally prepared through processes such a...
