摘要：

Experimental and crystal plasticity finite element modeling approaches are used to predict the deformation behavior of micropillar in the 16Mn steel. The intrinsic (crystallographic orientation) and extrinsic (friction coefficient on the micropillar) factors are considered for both experiment and modeling on the deformation behavior of micropillars. When the friction coefficient is low, buckling is occurred by slipping on the top surface of the micropillar, while barreling is accommodated in the high friction coefficient condition. In the multiple slip system, the influence of the friction coefficient is negligible on the deformation behavior of the micropillar because slip initiation can occur at multiple points.
