description: Graduation thesis: Â«Statistical analysis of mesoscale dendritic heterogeneity of aluminum alloys to model casting processesÂ». This work is devoted to research of existing methods of statistical analysis of foundry alloys dendritic heterogeneities, in particular aluminum-based alloys, their assessment to develop methods of more profound analysis of initial data and standardization of research methodology. The tasks that were solved during the study were:â Study of existing methods of data recording and statistical analysis of secondary interaxial gaps,â to study the accuracy of existing techniques for performing statistical analysis,â development of recommendations to improve the techniques and methods used, as well as the creation of tools for obtaining more information about the microstructure based on the raw data. The work is based on the study of published data on the performance of statistical analysis of secondary interaxial branches of samples from aluminum alloys (Al-5%Cu, AK12, etc.), some steels, which revealed the lack of a unified methodology of data analysis and incomplete use of all the existing apparatus of mathematical statistics, allowing to obtain more information about the studied microstructure. As a result, based on the studies, it is proposed to normalize the number of measurements taken from the samples, the application of the coefficient of excess and the accumulation of information on the studies carried out.
