8. Partial Dislocations in fcc Metals - (10 points) (a) (4 points) Calculate the equilibrium spacing of the Shockley partials in Cu due to the dissociation of a b=(110) screw dislocation (y = 40mJ/m²). (b) (4 points) Determine the radius of curvature at an extended node in Cu (also using y = 40mJ/m²). (c) (2 points) Which of the two measurements - i.e., the dissociation determined in part (a) or the radius of curvature calculated in part (b)- is easier to determine using transmission electron microscopy? Justify your answer.
