Abstract
Experiments are reported on the behavior of primary silica inclusions during the growth by isothermal coarsening of iron dendrites. The base alloy employed was Fe-50 pct Cu, chosen because of its wide freezing range. The inclusions are “pushed” by the growing dendrites. Also, the initially spherical inclusions collide and join with one another to form stringy “multimembered” inclusions. Partial coalescence occurs between touching inclusion members. A limited amount of diffusional coarsening of inclusions also occurs. It is suggested similar phenomena occur during dendritic solidification.
