31 Calculate the dislocation spacing and energy of a low-angle tilt boundary in Ni if ? = 0.5?, G = 76 GPa, r = 0.125 nm, ? = 0.31.
6.10 A Cu monocrystal (FCC) of 10 cm length is pulled in tension. The stress axis is [¯123].
(a) Which is the stress system with the highest resolved shear stress?
(b) If the extension of the crystal continues until a second slip system becomes operational, what will this system be?
(c) What rotation will be required to activate the second system?
(d) How much longitudinal strain is required to activate the second system?
