Essay

The methods of calculation of temperature-deformation parameters at hot extrusion of tubes of hard deformed alloys (determination of the temperature range of maximum alloy plastisity, deformation stress and extrusion force), methods of development of the processing tool design, correction and introduction of the tube production technology that ensures a wider size and alloy grade ranges and a higher efficiency of the tube production have been developed.
