New approach for modeling flow stress of aluminum alloy 6A10 considering temperature variation LI Xue-song(李雪松), WU Lai-zhi(伍来智), CHEN Jun(陈 军), ZHANG Hong-bing(张鸿冰) National Die...; Abstract: The flow stress behavior of aluminum alloy 6A10 was studied......
bending principle as the NC bender. The material is aluminum alloy LF2M and stainless steel (1Cr18Ni9Ti). Tube OD is 38 mm, wall thickness t is 1 mm, the length L is 600 mm and the bending radius R is 57... to investigate the plastic deformation. Because the stress distribution of stainless steel tube is similar to the aluminum tube, the tube materials are aluminum alloy LF2M in the following without......

constraint. The reason is that the inner tensile stress produced due to the constrained tube ends impairs the compressive stress in the inner arc of bending.Key words:aluminum alloy; hydro-bending; thin...Influence of tube ends constraint on hydro-bending of thin-walled aluminum tubeWANG Xiao-song, SONG Peng, ZHAO Zhong-yuan, YUAN Shi-jian(School of Materials Science and Engineering, Harbin Institute......
. This method not only conceives short processes, but also ensures the manufacture of the composite tube with excellent integration. Aluminum alloy A356 and magnesium alloy AZ91 were selected because...-extruded double layer tube is shown in Fig.6. As shown in Fig.6, after punch running of about 0.06s, the billets of aluminum alloy A356 and magnesium alloy AZ91 begin to contact with each other......
tubes under quasi-static loading conditions were studied. The foam-filled thin-walled square tube was fabricated with aluminum tube as its shell and closed-cell Al-Mg alloy foam as its core... was fabricated with aluminum tube as its shell and closed-cell Al-Mg alloy foam as its core. The transverse and longitudinal compression properties and energy absorption properties under quasi-static......
. The simulation result agrees with the experimental result, and the FLSD is able to predict the forming limit of tube hydroforming with remarkable accuracy. Key words: 3A21 aluminum alloy; hydroforming; fracture... corner and straight side. 4 Experiments on tube hydroforming Fig.10 shows the sample formed into a square cross- section with a 3A21 aluminum alloy extruded tube.
