Аннотация:The work is devoted to the application of the correlation analysis
method for the study of aluminum cast alloys; or rather, the relationship between
the density of a substance and the concentration of chemical elements in
it. The purpose of the work is to study the dependence of the density and concentration
of chemical elements in aluminum alloys to establish patterns of
growth and decrease in material density. The objective of the work is to determine
by the correlation method t he presence of a relationship between the density
and concentration of elements of chemical composition. The study was performed
by the method of correlation analysis using modern software tools, with
the help of which the dependencies between the physical parameters of alloys
and their chemical properties were searched. The study made a number of important
assumptions, detailed in the publication. As a result of the analysis, it
was revealed for which metals in the alloys the values can be processed by the
correlation method, and the corresponding point diagrams of the values were
constructed. Additionally, the accuracy of the research results was determined
by using manual and automatic methods. The study concluded that the density
of aluminum alloys depends on the concentration of magnesium. It is shown
that using the applied methodology it is possible to establish the accuracy correlation
between variables and determine the priority of certain additives in the
material. The publication is equipped with the necessary tables and figures, as
well as detailed explanations for each stage of the study.
