“…Besides, the modelling skill of dual mesh and hybrid mesh was used to improve the simulation accuracy and computational efficiency Ward, 2002b, 2003;Kim et al, 2013). Microstructure evolution during RARR was also tried by FE modelling methods (Yeom et al, 2010;Schwich et al, 2014;Zhu et al, 2014a). Through FE simulation, the deformation behaviour, forming laws and process parameters' effects during RARR were revealed visually (Qian et al, 2013c;Xu et al, 2013;Zhu et al, 2014b;Zhou et al, 2010aZhou et al, , 2011aZhou et al, , 2011bZhou et al, , 2012.…”
