Investigation of the microstructure evolution and properties of A1050 aluminum alloy during radial-shear rolling using FEM analysis

Microstructure evolution and property analysis of commercial pure Al alloy processed by radial-shear rolling

“…The values ln(Z) change from 36.5 to 40. In accordance with the distribution of deformation and temperature over rod cross-section during RSR [17], the maximal values ln(Z) are on the rod surface and decrease towards the center. The same character of distribution can be observed on distribution diagram of average size Fig.…”

“…6a. As can be seen the character of hardness change over cross-section is the same for all variants of rolling temperatures and corresponds to microstructure formed at RSR [15][16][17][18]. Microhardness has maximum values at the surface of the rod, then smoothly decrease towards the center and again increases in the axial zone.…”

“…The friction factor was chosen as a matter of RSR experience of aluminum alloys and coordination of rolling time in real process and modelling. Based on a number of experiments carried out earlier [16][17][18], the rolling time of a certain length bar was determined. In the simulation, a friction factor was selected that would provide the same rolling time as in the experiment to ensure the same slip.…”

“…As a result, the rods with a gradient functional structure were obtained. The authors [17,18] carried out the detailed analysis of temperature and deformation parameters of RSR based on FEM results and experimental rolling. The perspectivity for combination of piercing and RSR process for obtaining the pipes from copper alloys for electrical purposes is shown in [19].…”

Analysis of radial-shear rolling process parameters of aluminum alloys based on FEM modeling

“…Radial-shear rolling (RSR) is one of methods for producing of long rods from different steels and alloys. [13][14][15]. Due to macro-shear deformation, the deep working of material structure takes place in deformation zone.…”
