77376 If nucleation in nickel solidification is homogeneous, calculate the critical radius, if the latent heat of fusion and the surface free energy values are -2.53x10⁹ 109/m3and 255x10-3 J/m2, respectively. The degree of supercooling for homogeneous nucleation of nickel is 340°C. Nickel melting temperature is 1455C. [3]
