A metal with a lattice constant of a = 2.87 forms a grain boundary in a tilt angle of =5, the bond strength of the metal is 75 kJ/mol, deduce the surface energy of the grain boundary. Assuming the distance between dislocations is D as shown, Burgers vector is 2.5nm, calculate the dislocation density along the boundary per 1cm long.
