6.1 (a) Given a small-angle tilt boundary whose angle of tilt is 0.1, find the spacing between the dislocations in the boundary if the Burgers vector of the dislocations is 0.33 nm. (b) On the assumption that the dislocations conform to the conditions involved in Eq. 4.20, that r' = d/2, = 8.6 1010 MPa and v = 0.3, determine an approximate value for the surface energy of the tilt boundary. Give your answer in both J/m and ergs/cm. 6.1 (a) Given a small-angle tilt boundary whose angle of tilt is 0.1, find the spacing between the dislocations in the boundary if the Burgers vector of the dislocations is 0.33 nm.
