An analysis of the dispersity of Al3Mg2 inclusions in annealed aluminum-magnesium alloys

A description of the system analysis of the kinetics of the coarsening of dispersed phases due to the Ostwald ripening of microparticles and related processes is given. For this purpose, the similarity and difference between the experimental and theoretical size distribution of microparticles are preliminarily established via a comparison of the characteristics of distributions and corresponding moments. This method of identifying distributions allows one to reveal the correlation between the features of the transformation of experimental distributions (histograms) and processes in a dispersed system. The objects of structural microanalysis were the data on the size distribution of Al 3 Mg 2 microparticles obtained after heating the aluminum-magnesium alloy at temperatures of 350, 400, and 430°C.
