Set-up of radial–axial ring-rolling process: Process worksheet and ring geometry expansion prediction

“…Based on the actual RARR production conditions, the range of K considered is from zero to one [8]. Fig.…”

Recent development of ring rolling theory and technique

“…In early days, limited by the study condition, the researches on RARR were scarce. Currently, based on the research of RRR, the scholars, such as Hua L. at Wuhan University of Technology (Hua et al, 2009a;Zhou et al, 2010aZhou et al, , 2011bZhou et al, , 2012, Yang H. at Northwestern Polytechnical University (Guo and Yang, 2011;Zhu et al, 2014b), Li Y.T. at Taiyuan University of Science and Technology (Li et al, 2014b), Allwood J.M.…”

“…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. Furthermore, to reveal the genetic effects of blank forging to ring rolling, macro-microscopic deformation laws during blank forging and ring rolling process were explored (Qian and Pan, 2013).…”

Modeling and application of ring stiffness condition for radial-axial ring rolling

“…Simulations of microstructure evolution during RARR have been also tried [16][17][18]. By FE simulation, deformation behaviors during RARR and effects of technological parameters on RARR process have been revealed systematically [19][20][21][22][23].…”
