The purpose of the work is to create theoretical foundations and processes and a pilot plant for isothermal shaping under conditions of viscoplastic deformation of parts with thin-walled elements made of titanium alloys and powder materials.
The work analyzes the use of parts made of titanium alloys in high-tech mechanical engineering structures - aviation gas turbine engines. Typical representative parts with thin-walled elements (blades, disks, monowheels) were selected. A general theoretical method has been developed for calculating the processes of forming thin-walled elements of parts, including the use of the theory of plastic flow for viscoplastic deformation of metals.
A method for controlling the structure and mechanical properties of titanium alloys using the deformation method was considered.
The influence of hot stamping operations on the structure and properties of titanium matrix composites is considered, namely: the influence of hot stamping on the elastic properties and the nature of anisotropy of powder titanium matrix composites; the influence of the component composition of the charge on the structure and properties of sintered titanium matrix composites with high modulus compounds; the influence of mechanical activation modes of the charge on the structure and phase composition of sintered multicomponent titanium-based composites, etc.
An analysis of the influence of the temperature factor on the conditions of deformation during the implementation of isothermal processes using numerous calculation methods using viscoplastic models was carried out.
approbation of results, such as calculation methods for parameters of technological processes of compressor blades of monowheel discs GTD D-16 AI 222-25; design of installation for isothermal movement for titanium alloys and powder materials; a number of recommendations for: implementation of technological processes for isothermal stamping of aircraft engine parts from titanium alloys OT4, VT6, VT8.
