(a) With regard to the coincident site twist boundary on a {111} fcc metal plane shown in Fig. 6.25, show that using the Ranganathan relationships (Eqs. 6.21, 6.22 and 6.23), that a choice of x = 2 and y = 1 will also give this ?=7 boundary.
(b) To what angle of twist does x =2 and y = 1 correspond? (c) Is the fact that x = 2 and y = 1 are able to produce an equivalent coincident site boundary to that in Fig. 6.25 related to the symmetry of the atomic arrangement on the {111} plane? Explain.
