Fig.1 Secondary electron (SE) images and inverse pore figures (insets) (a-c), corresponding schematics of slip planes (d-f), and electron channeling contrast imaging (ECCI) images and corresponding schematics (insets) (g, h) of grains with different orientations under 80 mN indentation load (P represents positive inclined, N represents negative inclined. Boxes 1, 2, and 3 in Figs.1a and c represent regions where double cross-slip exists. In Figs.1d-f, white lines represent the intersection line between the slip planes and the surface, which are the slip steps; bolded portions at the edges of the slip planes represent the angles closer to the sample surface, indicating the inclination angles between the slip planes and the surface) (a, d, g) {101} grain (b, e) {111} grain (c, f, h) {001} grain
