Kinetic control of the width of RB-NWBA as a function of cooling rate (vcooling) in a strong hypereutectic regime (fBA = 0.9); (a) W = 755 ± 90 nm at vcooling = −5 °C/min, (b) W = 358 ± 48 nm at vcooling = −10 °C/min, (c) W = 199 ± 42 nm at vcooling = −15 °C/min, (d) W = 78 ± 25 nm when the temperature was abruptly dropped from 130 °C to 25 °C.
