Experimental studies of forming and energy-power parameters of the process of joint rolling-extrusion of rods made of aluminum alloys

摘要

The results of the studies of a new joint rolling-extrusion process characterized by active friction forces for production of aluminum alloy rods are given. Metal forming features with joint rolling-extrusion method are described The results of experimental studies to determine forces affecting rolls and die during deformation of a bar made of alloys of the Al-Ti-B system as well as AD and AD31 alloys are given Dependences of sought quantities on such parameters as drawing, deformation fate, bar heating temperature reduced diameter of rolls, etc have been found.
