SOLVED:(a) Prove that the ideal c /a ratio for the hexagonal close-packed structure is √(8 / 3)=1.633. (b) Sodium transforms from bec to hep at about 23  K (the "martensitic" transformation). Assuming that the density remains fixed through this transition, find the lattice constant a of the hexagonal phase, given that a=4.23  A in the cubic phase and that the c / a ratio is indistinguishable from its ideal value.

Fig. Q4 shows a hexagonal close packed structure (hcp).(a) Show that for an ideal hcp, (c)/(a) = 2√((2)/(3)) = 1.633.(8 marks)(b) Show that the packing ratio (or packingefficiency) of hcp is the same as that of fccstructure, that is 0.74.(10 marks)(c) α-Co has an hcp structure with lattice spacinga = 2.51 Å and c = 4.07 Å, whereas β-Co isfcc. What is the difference in density (in %)between the two forms? (Hint: α-Co obviouslydoes not have ideal hcp structure. Refer youranswer in (b) to see how c
