SOLIDIFICATION OF IRON BASE ALLOYS AT LARGE DEGREES OF UNDERCOOLING

Abstract

The report summarizes one of several related research activities on inclusions. The work is primarily on levitation melted and rapidly solidified (including splat-cooled) samples. It deals with effects of solidification variables on (1) dendrite and inclusion structures, (2) influence of high temperature homogenization treatments on inclusions, and (3) influence of inclusions on fracture behavior of iron. The research is an outgrowth of a program on undercooled iron base alloys, that has had important technological, as well as fundamental, findings. Dendrite arm spacing is of major importance in determining properties of castings and of wrought material produced from cast ingots and so determination of the mechanism of establishment of dendrite arm spacing has been of considerable applied as well theoretical interest.
