RELATIONSHIP BETWEEN SEGREGATION SUBSTRUCTURES AND CASTING STRUCTURES.

Abstract

Evidence is presented relating to the impossibility of micropore formation in the cellular substructure by a microshrinkage mechanism. A study is made of the detailed relationship between solidification substructure and microsegregation in dilute tin alloys. A method of investigating the instability of interfaces when Constitutional Supercooling exists in ternary alloys is developed. Interaction among the solutes under non-ideality conditions is considered. A cold microscope stage is developed for the study of predendritic growth in organic compounds such as ciclohexanol and carbon tetrabromide. The effect of scale up the ingot's size on structure and substructure is studied. Three sets of ingots of approximately 50 cc., 500 cc. and 5000 cc., is investigated.
