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 andor 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.
