Computer Simulation of Kinematics of Plastic Flow and the Deformed Condition of Metal at Processes Equal-Channel Angular Pressing

Abstract:

Object of researches in the given paper is the technological process of obtaining from carbon steel method equal-channel angular extrusion (ECAE) on one pass. The purpose of theoretical research is the working of recomdations on projection of the process with the help of a designed technique of simulation of process ECAE in CAE systems. Calculations were done under variable conditions ECAE over the range changes of parameters: a corner of intersection of channels Ф from 90 up to 150 grades, speed of driving press from 0,05 m/s up to 0,2 m/s, temperature from 20°С up to 600°С. As a result quantitative links of local parameters (stresses, strains and temperature) are established with geometrical and technological ECAE parameters to one separate pass. Regularities of change of parameters to ECAE process of cylindrical preforms in diameter of 20 mm and 30 mm are established (steel 0,15%С), are investigated; character of change of a tension in the instrument and power conditions of the process was studied.
