Abstract
One weakly coupled growth mechanism, cellular peritectic coupled growth (CPCG), was observed recently during the directional solidification of peritectic alloys, which can be a candidate method to produce well aligned in situ composites in peritectic systems. Directional solidification experiments were carried out in Fe–Ni peritectic alloys to investigate the characteristic spacing of CPCG. It was found that the cellular spacing of CPCG first decreases with increasing velocity and then increases with increasing velocity. A simplified model was developed to predict the cellular spacing of CPCG. Good agreement was obtained between the predictions and experimental results in Fe–Ni alloys.
