Abstract
The local deformation process of blanks in the form of thin discs made of titanium VT6S alloy with the use of pulse heating with electric current without and with deformation in heated state in the electrodes of the point contact welding machine is studied. It is established that when heated without deformation, increase in the temperature of heating contributes to the growth of grain in the blank. Intense grain growth is noted at heat temperature above 750...800 °C. Intensive plastic deformation due to the compression of the blank heated area by the electrodes of the contact machine is accompanied by the formation of double layers and decrease in the size of the grain after deformation and artificial ageing.
