“…The available research [1][2][3][4][5][6][7][8][9][10][11] confirms the positive changes in the mode of the metal flow when using the pocket dies of proper geometry. Zasadzinski et al [1] examined extrusion of section having varying wall thickness and proposed the use of pocket at the thicker part of the section only, guarantying its dimensional stability.…”

“…Zasadzinski et al [1] examined extrusion of section having varying wall thickness and proposed the use of pocket at the thicker part of the section only, guarantying its dimensional stability. Misiolek and Prats [2] determined the pocket height to diameter ratio H/D, that gives the most uniform metal flow and the minimum of extrusion force.…”

The electron backscatter diffraction (EBSD) technique is used to analyze the crystallographic grain orientation of deformed microstructures for 6xxx series aluminum alloy extrusions. In a partially extruded billet of aluminum, deformation zones with different crystallographic characteristics can be seen. Using compression testing performed on a Gleeble thermal-mechanical simulator under various conditions, the formation of different deformation zones is simulated. The EBSD technique is used to characterize samples deformed in compression testing to analyze the different deformation zones present in the extrusion process. Metal-flow analysis using EBSD is also applied to study the influence of different die designs on the surface texture of an extrudate. Microstructures from a profile that was formed with different die designs are examined. Analysis of a longitudinal weld present in typical hollow profiles is performed to determine the effect of metal-flow conditions on the resultant texture in the extrudate. The texture (or microtexture) measured from individual grains can be correlated to the orientation changes that occur during deformation.

“…One of the most important points for straight-fin extrusion is the flow balance because an unbalanced metal flow will result in extruded fins of different lengths. Zasadzinski et al (1989) investigated the influence of weld cavity geometry on metal flow during the extrusion process of asymmetric shapes. Ulysse and Johnson (Ulysse, 1999) adopted the finiteelement method combined with techniques of mathematical programming to propose an optimal extrusion die design procedure for achieving flow balance.…”
