Abstract
The technological parameters of tube extrusion of 7075 Al alloy,such as slug temperature,tools temperature,choice of lubricant,ratio of extrusion,and extrusion speed,have been determined by experiment in this paper.It is analyzed that microstructure performance of 7075 Al alloy tube extrused.The extrusion force and influence factors have also been studied.From the results of experiment,it is found that extrusion force has relation to deformation temperature,tool temperature,ratio of extrusion,lubricant and deformation velocity.
