Abstract Finite element simulation was carried out for analyzing the accumulative rate of equivalent strain and final equivalent strain of 5052 aluminum alloy processed by constrained groove pressing (CGP) and unconstrained groove pressing (UGP). In addition, experiments were conducted for investigation of grain refinement as a function of accumulative rate of equivalent strain as well as final equivalent strain. The results show that CGP has a higher accumulative rate of equivalent strain and final equivalent strain than UGP. Compared with UGP, CGP is more beneficial to grain refinement due to the higher accumulative rate of equivalent strain and final equivalent strain, which is determined by two different mold constructions and independent of the material and processed condition.
