主 题:AZ31 Mg alloy 6061 Al alloy Compound extrusion Crack EBSD
摘 要:A novel and effective method to co-extrude metallic alloys is described which named Direct Extrusion and Bending-Shear *** compound extrusion plates have cracked at 290℃ and 3 mm/*** to this phenomenon,a model was built to investigate the crack generation and development between the 6061 Al and AZ31 Mg alloy during the compound extrusion process by *** cracking behavior of the Mg/Al composite rod with a soft Mg AZ31 core and a hard Al 6061 sleeve were systematically studied to disclose the influence of microstructure on crack in the different *** simulation results show that the distribution of strain and velocity has significant differences due to the influence of dies structure and material properties at different locations in the same *** experimental results show that in the same conditions,there are differences in recrystallization and texture weakening of AZ31 Mg alloys and 6061 Al alloy,which are important factors for the formation of *** the Mg layer and the Al layer have a homogeneous microstructure in the region d.
