of Technology, Harbin 150001, China Received 9 July 2012; accepted 10 August 2012 Abstract: To analyze the effect of single grain deformation behaviors on microforming process, a crystal plasticity model was developed considering grains at free surface layer as single grains. Based on the rate-dependent crystal plasticity theory, the analysis of the scale effect mechanism on upsetting deformation......
