description: This work is devoted to the development of technology for manufacturing pipes from titanium alloys with an ultrafine-grained structure for new generation power plants.The research set the following goals:
1 Analysis of the influence of the degree of deformation and heat treatment on the structure of pipe blanks of titanium alloy PT-7M.
2 The study of the influence of heat treatment and grain size on the mechanical properties of pipes made of titanium alloy PT-7M.
3 Microstructural studies of pipes manufactured using standard technology and with a fine-grained structure.
4 Determination of the texture and crystallographic orientations of the structure of the metal pipes made by different technologies.
5 Development of guidelines on the manufacturing technology of cold-deformed pipes with a fine-grained structure.
The work was fulfilled on the premises of NITS "Kurchatovskij institut" - TSNII KM "Prometej", where the results of metallographic analysis of the samples were obtained, mechanical characteristics were determined. The results obtained are analyzed on the basis of theoretical data, graphical dependencies are constructed, showing the laws of changes in properties of the annealing temperature, the influence of heat treatment temperature on the structure, grain size and texture. Technological recommendations for the manufacture of pipes with a fine-grained structure were developed.
