| Title: Mathematical analysis and its experimental comparisons for the accumulative roll bonding (ARB) process with different superimposed layers | |
| Abstract: Based on the traditional two-layer accumulative roll bonding (TARB), the geometrical variations and mathematical relationship during the four-layer accumulative roll bonding (FARB) were derived and summarized. Furthermore, the multi-layer accumulative roll bonding (MARB) technology was proposed and the geometrical variations and mathematical relationship of MARB were simultaneously derived and summarized. Experimentally, Mg-14Li-3Al-2Gd (LAGd1432) sheets were fabricated by TARB and FARB, respectively. The relationship between equivalent strain and mechanical properties and the relationship between grain refinement and accumulative efficiency are established. Compared with the TARB, the FARB has a higher accumulative efficiency in terms of accumulative layers, total number of interfaces, interface spacing, total deformation and equivalent strain, which leads to the excellent performance of FARB under low cycles. Keywords: ARB; mathematical relationship; equivalent strain; strengthening mechanism | |
