Characteristics of Large Bars Extruding Using Small Extrusion Ratio

Abstract:

Computer analysis of distribution of stress intensity and strain intensity in different cross sections of plastic deformation region and in finished material in the course of hot extruding process was carried out. By means of the finite element method in the Deform-2D program influence of small extrusion ratio value on stress-strained state of large 250mm to 500mm dia. bars in 7075 high-strength Aluminium alloy was established.
