| Abstract: | Through analysing the sphere model stability with the sphere disturbance and transforming the radius of the sphere into the radius of curvature crystal MC carbides growing from melt of nickel-base superalloys are discussed. The MC carbides morphology of growing branches from octahedrnm are worked out and that are in accordance with the experimental morphology which are seen through SEM technique. |
