The data of the article "Effect of trace Mg and heat treatment on microstructure and properties of Al-7Si alloy"

This article investigates the effects of Mg and heat treatment on Al-7Si alloy through methods such as SEM, TEM, conductivity testing, tensile testing, and microhardness testing. The dataset obtained in this article mainly includes SEM and EDS characterization source files of the original images 1, 2, 3, 5, and 6, as well as the TEM original image of Figure 9, which have been uploaded in. tif and. pdf formats and can be opened directly. In addition, the test raw data used in Figures 4, 7, 8 and Table 3 were uploaded, and the meanings of the data in the table were explained in the form of. csv files. Figures 4, 7, and 8 in the text were all obtained by Origin software processing the raw data. Each file name uploaded corresponds to the corresponding image or table in the original text. "Figure 1, Figure 5" corresponds to the EDS data in Figure 1 and Figure 5 of this article, "Figure 2, Figure 6 SEM" corresponds to the SEM data in Figures 2 and 6 of this article, "Figure 3" corresponds to the data in Figure 3 of this article, "Figure 4, Figure 7, Figure 8 and Table 3 Original Data" corresponds to the relevant data in Figures 4, 7, Figure 8 and Table 3 of this article, and "Figure 9 TEM" corresponds to the relevant data in Figure 9 of this article.
