Соотношения радиальных и тангенциальных деформаций в процессе прессования

Abstract

According to the computer simulation results of titanium alloys extrusion and x-ray analysis it was proved that there is a connection between components of a deformation tensor and texture parameters that characterize crystal orientations in a treated material. The unevenness of texture in extruded billets was found. The way to control the texture based on input and output billet geometry change was proposed. The formulas for components of the strain and strain rates applied to the rod blanks extrusion of alpha-titanium alloys. Finite element method calculated the tensor components, which showed no coincidence of the tangential and radial component. Mathematical modeling showed that the prevalence of one or the other component is a function of radial coordinate and extrusion ratio. Worded forecast receipt in the peripheral layers rod, a radial texture in the range of industrially applicable extrusion ratio.
