The paper notes the relevance of using aluminum for the production of drill pipes. One of the problems in the production of drill pipes with tread thickening is also presented - the formation of a defect such as “streak delamination” in the tread formation zone. Pipes with internal end and tread thickenings made of D16T alloy were selected as the object of study. As an experiment, two variants of the pressing process were carried out: in the first - the temperature of the metal of the workpiece is 440°C, in the second - 400°C, in the first - the speed of movement of the punch during pressing of the tread is 1.4 mm/s, in the second - 0.9 mm/s. It has been experimentally established that lowering the temperature of the workpiece metal by 40°C and the speed of movement of the punch during tread pressing by 0.5 m/s promotes the formation of a homogeneous macrostructure. By modeling the described variants of experimental processes, it was established that a decrease in the temperature of the workpiece metal by 40°C and the speed of movement of the punch during tread pressing by 0.5 m/s leads to a decrease in the maximum value of the deformation rate in the deformation zone by 50%, and a decrease in the degree of deformation by 14 %. Calculation of the state indicator in the deformation zone makes it possible to establish that the metal in the second version of the process has a more favorable state of the state compared to the first, which can also lead to a decrease in the number of defects such as“streak delaminations” in the open tread.
