Figure 1

High-speed camera images of recalescence front of undercooled Ni83.25Zr16.75 peritectic samples at different undercoolings.
The red part is the undercooled liquid, and the yellow part is the recalescing solid. The time interval between two adjacent images is 24 ms and 8 ms, respectively. (a) ΔT = 58 K; (b) ΔT = 132 K.
