The object of research - the phenomenon of electrochemical phase formation in metals via a supercooled liquid state stage. The purpose of the work is to experimentally verify the existence of the phenomenon of electrochemical phase formation in metals via a supercooled liquid state stage and to determine the direction of use of this phenomenon in space rocket technology. Methods of investigation - X-ray phase analysis, X-ray texture analysis, scanning electron microscopy, test of adhesive strength. As a result of performing the third (final) stage of the research work, the following scientific effects were established: the effect of electrochemical phase formation of polymorphic metals in the form of metastable modifications, which is characteristic for metals crystallized from a liquid state at very high speed; the effect of adhering to a certain orientation ratio between grains of stable and metastable modifications of electrodeposited polymorphic metal, which is characteristic for phase transitions occurring at very high speed. Scientific and technical products have been created: “New concept of phase formation of metals during electrocrystallization (part 3)”. The direction of practical use of the established phenomenon in space rocket technology is determined. On the basis of generalization of the obtained results the existence of the phenomenon of electrochemical phase formation in metals via a supercooled liquid state stage has been proved and the formula of scientific discovery has been presented. Scientific and technical products have been created: “Phenomenon of electrochemical phase formation in metals via a supercooled liquid state stage”. The field of application of the results of work: C 25.61 – processing of metals and applying of coating on metals.
