description: Topic of graduation qualification work: "Analysis of dendritic heterogeneity of casting alloys."
This work is devoted to the analysis of dendritic inhomogeneity of the first and second kind in foundry alloys, as well as the consideration of models studying this dendritic inhomogeneity and its effect on foundry alloys. The tasks that were solved during the analysis:
1. Consideration of dendritic heterogeneity of the first kind and analysis of the causes of their occurrence.
2. Consideration of the dendritic heterogeneity of the second kind and analysis of the causes of their occurrence.
3. Presentation and discussion of mechanisms, patterns, models and experimental data on the study of dendritic heterogeneity and its effect on the formation of castings and properties of casting alloys.
4. Research perspectives on the problem and possible models to address them.
The work analyzed the heterogeneity of the dendritic structure both before the closure of the branches and after. The effect of the distance between the second-order dendritic branches on dendritic heterogeneity was revealed. Models showing influence of dendritic inhomogeneity, in particular distance between dendritic branches of the second order, on casting structure are considered. The prospects for further study of dendritic heterogeneity and its effect on the quality of castings are indicated.
