EFFECT OF THE POLYMORPHIC TRANSFORMATION TEMPERATURE ON CHANGE IN THE STRUCTURAL HETEROGENEITY OF TITANIUM ALLOYS DURING SCREW PRESS FORMING
The paper considers influence of the polymorphic transformation temperature (PTT) on the change in the structural heterogeneity of titanium alloys when screw press forming. Also the microstructure of specimens after deformation of titanium samples (TV6V, VT3-1, VT6, and VT8) with different degrees of deformation and different temperature of specimen heating was considered. The optimal parameters of deformation of titanium alloys were determined according to the results of the experiments.
