RETRACTED: Effect of Final Rolling Temperature on Microstructures and Mechanical Properties of AZ31 Alloy Sheets Prepared by Equal Channel Angular Rolling and Continuous Bending

Abstract

The effects of final rolling temperature on the microstructures, texture and mechanical properties of AZ31 Mg alloy sheets prepared by equal channel angular rolling and continuous bending (ECAR-CB) were investigated. Extension twins {10–12} could be observed in the ECAR-CB deformed sheets. The increase in the number of {10–12} extension twins with increasing final rolling temperature might be attributed to the larger grain size and faster grain boundary migration. For all the ECAR-CB sheets at different final rolling temperatures, the deformation texture contains a basal texture component and a prismatic texture component, whereas the annealing recrystallization texture becomes a non-basal (pyramidal) texture with double peaks tilting away from normal direction (ND) to rolling direction (RD). With increasing final rolling temperature, the tilted angle of double peaks of annealing recrystallization non-basal texture increases. In addition, the plasticity and formability of ECAR-CB-A (ECAR-CB and then annealing) AZ31 Mg alloy sheets at room temperature can be improved by increasing the final rolling temperature.

Case study of advanced processed OFHC copper by dry sliding wear test

“…In the ECAR, DOI: 10.36547/ams.29.1.1734 metal sheets are subjected to shear strain through the die channels without changing the dimensions [30][31][32][33][34][35]. The final rolling temperature increase could improve plasticity and formability [36]. Orbital forging is a metal forming process which incrementally deforms a work-piece using a combination of rotation, rolling, and axial compression processes.…”

Study on Microstructure and Properties of Single‐Pass Online Heating Rolling of Mn‐Containing Magnesium Alloy Sheets

“…[ 4,9 ] Therefore, improving the rolling forming performance, through advance rolling technology, and further obtaining the magnesium alloy sheet with excellent mechanical property is an urgent task. At present, the rolling methods mainly include cumulative overlapping rolling, [ 10–12 ] asymmetric rolling, [ 13,14 ] equal‐diameter angular rolling [ 15–18 ] cross rolling, [ 19,20 ] etc. In our previous research, it is found that the online heating rolling technology has the characteristics of high efficiency and immediacy heating, which reduce energy consumption and simplify the operation process, leading to the decrease in the tendency of the edge cracking of the rolling sheet.…”
