The Department No. 9 “Physical Problems of Materials Science” project led by Ivan Vladimirovich Fedotov, “Study of the structural-phase state in a composite amorphous-crystalline zirconium-based alloy produced by melt casting into a mould”, has won a competition held among young scientists and research groups led by young scientists at NRNU MEPhI. The project is devoted to studying the melt crystallisation process in order to establish the critical cooling rates for transitional amorphous-crystalline structures. The results obtained will make it possible to predict printing regimes for producing bulk amorphous-crystalline alloys using the SLM method.
Studying the characteristics of the transitional amorphous-crystalline structure formed in cast ingots will make it possible to determine the target cooling parameters of the melt obtained during selective laser melting. Implementation of the project will allow scientifically grounded approaches to controlling the microstructure and properties of amorphous alloys, including BMGCs, to be developed, and will create a basis for the industrial application of SLM in producing bulk amorphous products with enhanced ductility and a specified microstructure. The relevance of the project stems from the growing interest in additive manufacturing and the need to develop new materials with improved properties for high-tech industries such as aerospace, medicine and others.
