Grain Refining and Microstructural Modification during Solidification.

Abstract

This report summarizes progress during the 1984-1985 fiscal year of a research program to study grain refining and microstructural modification during solidification, as affected by supercooling, solidification rate and/or innoculation. The report covers results of the current investigations on the kinetics of peritectic reactions during solidification of binary Al-Ni alloys, and high temperature phase transformations in binary Cr-Ni alloys. In addition, the report contains results of three other completed projects related to grain refining in Cu-Fe alloys, thermomechanical processing of rapidly solidified Al-Li-Mg-Zr alloy powder, and purification of Nb by electromagnetic levitation melting. Keywords: electromagnetic; stirring; peritectic alloys; Volume fractions; Aluminum intermetallic; Nickel intermetallics; Phase diagrams. (Author)
