“…where DT 0 is the temperature difference between the tip and the nonequilibrium solidus and V cd is the critical growth velocity for the transformation from cellular to and several exponent values of 0.40, 0.50, 0.27, and 0.54 were obtained in different research works. [41][42][43] So, it is reasonable for a larger exponent value to be obtained for seaweed growth. The tip-splitting frequency f of b-Co 3 Sn 2 seaweed vs growth velocity follows a power law relationship, and fitting of the experimental results gave exponents of 1.46 and 1.41.…”

Co 70 Sn 30 hypereutectic alloy was directionally solidified at various velocities at temperature gradients of 200 and 300 K/cm. At a given temperature gradient, a-Co/b-Co 3 Sn 2 lamellar eutectic grows with a planar interface when the withdrawal velocity is small. The increases of withdrawal velocity result in primary b-Co 3 Sn 2 phase growing ahead of the eutectic, and its morphology changes from dendritic pattern to fractal seaweed pattern above a critical withdrawal velocity. The rise of the temperature gradient narrows the withdrawal velocity range within which primary b-Co 3 Sn 2 phase can grow in the dendritic pattern. The tip-splitting frequency of the b-Co 3 Sn 2 seaweed vs growth velocity shows a power law f / V 3=2 The change of the primary arm spacing of b-Co 3 Sn 2 with the growth velocity follows d 1 ¼ k 1 V Àe 1 ; where the exponent e 1 is larger for seaweed growth than for dendritic growth.

“…The exponent value of the growth rate b is equal to 0.26 and 0.24 for the Al-0.1 wt% Ti and Al-0.5 wt% Ti alloys, respectively. Decreasing of cellular spacings, λ with increasing growth rates, V was determined by various workers for different alloy systems [6,77,84,[93][94][95][96][97][98].
