Abstract

The analysis of literature data about the technological parameters of AMg2 alloy extruded profile production is carried out. The effect of the porthole die design on extrusion force and effect of heat treatment on the mechanical properties of pipes are determined based on experimental studies of small-diameter pipe extrusion (14×1.5 mm) at the press line of JSC “Dniprovskiy factory “ALYUMASH”. Metal forming in the porthole die and temperature distribution in the deformation zone are studied by finite element simulation.
