Engineering Materials Week 7 10.4 (a) For the solidification of nickel‚ calculate the critical radius r* and the activation free energy ∆G* if nucleation is homogeneous. Values for the latent heat of fusion and surface free energy are -2.53 X10⁹ J/m3 and 0.255 J/m2. (b) Now calculate the number of atoms found in a nucleaus of critical size. Assume a lattice parameter of 0.360 nm for solid nickel at its melting temperature. (116 unit cless/critical nucleus)(4 atoms/unit cell)=464 atoms/critical
