本文研究了在1400°C下，Y_2O_3稳定的氧化锆中，通过使晶体沿晶向(<001>、<115>、<113>和<029>)形变，激活了二次滑移系{110}<1·0>和{111}<1·0>，其中初级(001}<110>)晶系的施密德因子较低。{110}和{111}滑移的临界分辨剪应力几乎相同，比{0 0 1}滑移的临界剪应力高出约⅓。
Abstract Activation of secondary slip systems, {110} 〈1·0〉 and {111} 〈1·0〉, have been studied in Y2O3-stabilized ZrO2 at 1400°C by deforming crystals along orientations (〈001〉, 〈115〉, 〈113〉, and 〈029〉), for which the Schmid factors for the primary ({001} 〈110〉) system are low. The critical resolved shear stresses for {110} and {111} slip were nearly identical and about ⅓ higher than for {001} slip.
