description: The subject of the graduate qualification work is Â« Study of the peculiarities of the formation of the microstructure of alloys with the shape memory effect based on ironÂ». The given work is devoted to studying of shape memory alloys based on the Fe-Mn-Si system. The research set the following goals: 1. Study of the features of reversible martensitic transformation in iron-based alloys with shape memory effect. 2. Determination of the nature of the influence of alloying elements on the properties of the alloy. 3. Study of the features of smelting and casting alloys with SME based on iron. 4. Determination of the possible application of iron-based SME alloys. 5. Investigation of the resistance of alloys to the formation of hot cracks. 6. Investigation of the features of the cast microstructure of an iron-based SME alloy. In the course of the work, the resistance of the Fe-35Mn-8Si alloy to the formation of hot cracks was investigated and the features of the formation of the cast structure of this alloy were studied. It was found that the Fe-35Mn-8Si alloy has low crack resistance, since such alloys crystallize through the primary austen-ite dendrites, in which the processes of liquation accumulation of impurities are developed. It was determined that the experimental alloy has a high degree of seg-regation, which requires further processing of the alloy to reduce the chemical heterogeneity.
