J. Cent. South Univ. Technol. (2009) 16: 0738-0742 DOI: 10.1007/s11771-009-0122-3 Deformation division of metal flow behavior during extrusion process of 7075 aluminum alloy LI Feng(李 峰)1, CHU...; Abstract: To reduce defects caused by non-homogeneous metal flow in conventional extrusion, a die with guiding angle was designed to improve the metal flow behavior......
Effect of Extrusion Forming on Compressive Strength of Al_(18)B_4O_(33)w/Mg Composites () 摘要:The aluminum borate whisker reinforced magnesium matrix composites (Al_(18)B_4O_(33)w/Mg) were fabricated by pressure infiltration technique and extrusion-vacuum infiltration technique respectively to study the effect of extrusion forming on their mechanical behaviors. The microstructure......

Dispersion of Co-poly Carboxylate Superplasticizer Containing Poiyether Side Chain左彦峰,王栋民摘 要:<正>Free radical co-polymerization was employed to synthesize co-poly carboxylate (PC) su-perplasticizers with different amount of carboxyl and methyl polyethylene glycol (MPEG) side chain. Dispersion ability and retention of PC were compared with one......
AN ADAPTIVE EFG-FE COUPLING METHOD FOR THE NUMERICAL SIMULATION OF EXTRUSION PROCESSES X.H.Dong1,L.C.Liu1,C.X.Li1 (1.National Die & Mold CAD Engineering Research Center,Shanghai Jiaotong University,Shanghai 200030,China) Abstract:An adaptive EFG-FE coupling method is proposed and developed for the numerical simulation of lateral extrusion and forward-backward extrusion. Initially......
channel angular processing (ECAP) and porthole die extrusion techniques, a novel technique, namely portholes-equal channel angular processing (P-ECAP), was studied. Extrusion of AL6005A plate used... obtained after extrusion from the P-ECAP die, with different channel angles, were predicted. Effects of the channel angle and extrusion speed on the maximum temperature of the workpiece and other field......
