a Maximum resolved shear stress as a function of the rotation angle of SD around the fixed ND, designated \(\varphi\). An angle \(\varphi\) equals to 0° corresponds to a SD of \([100]\), and \(\varphi\) equal to 225° to \([\bar{1}10]\).The resolved shear stress distribution maps of various stress components of the twin systems \(\left(\bar{1}11\right)\) \([\bar{1}1\bar{2}]\) in (b) and \(\left(\bar{1}1\bar{1}\right)\) \([\bar{1}12]\) in (c) at ND \([00\bar{1}]\) SD \([\bar{1}10]\) are presented. The angle—thus sliding direction—and twin systems are marked in (a). Additional stress distribution maps are presented in Supplementary Fig. 4. The contact point of the two bodies making up the tribological system is at a distance of 0 µm. Positions in front of the contact point with respect to SD take positive x-values.
