Titanium goes through an allotropic transformation from BCC to HCP crystal structure on cooling through 882°C. Calculate the percentage change in volume per atom when the crystal structure changes from BCC to HCP. The lattice constant of the BCC unit cell is a= 0.332nm, and the HCP unit cell has a=0.2950nm and c=0.4683nm. The percentage volume change is given by [(Vf-V₁)/Vi]x 100 where Vf is the final volume and Vi is the initial volume. If expansion indicate with " +" or if contraction indicate with "-"
