Experimental Determination of Temperature Parameters for Evaluating the Possibility of Manufacturing Alloy Ti–3Al–2.5V Hot-Extruded Tubes

Аннотация

Microstructural methods, thermal analysis, and thermomechanical test methods are used to study the structure and properties of hot-pressed semifinished product of alloy Ti–3Al–2.5V used for developing manufacturing technology for hot-extruded tubes. It is shown that the use of calculation methods for evaluating polymorphic transformation temperature makes it possible to assess the required temperature range with use of a test quenching method. Thermal analysis and laboratory thermomechanical tests are used to determine the temperature range for extrusion in two regions taking account of deformation heating.
