摘要	Deformation behaviors of [110] and [112] oriented Sn single crystals were investigated under different. temperatures and strain rates. It is shown that there are some differences between [110] and [112] orientations. [110] oriented sample has the higher strain rate sensitivity exponent, m approximate to 0.133, strain hardening exponent n approximate to 0.54, activation energy Q approximate to 35 kJ/mol and deforms through multiple-slip. While [112] oriented sample has the lower strain rate sensitivity exponent m approximate to 0.108, lower strain hardening exponent n approximate to 0.46, activation energy Q approximate to 52 kJ/mol and deforms through cross-slip and twins together. The first activated slip system is {010} < 100 > in [110] orientation. The critical-resolved shear stress (CRSS) is 3.1 MPa which is depended on temperature. Deformation process is controlled by the cross-slip according to the activation energy and slip observation.
