Critical Dynamics for Continuous Rapid Solidification Processing.

Abstract

Quantitative measurements of melt puddle dynamics and the associated characteristics of continuously solidified ribbon products were made as a function of materials combinations and processing conditions. A three-phase approach was taken to separately evaluate the effects of processing parameter variations, of melt chemistry, and of substrate composition. In Phase 1 two processing parameters, the melt delivery rate and the circumferential wheel velocity, were systematically varied for metalloid solute/ nickel-base alloys with Ni-12.8 a/o B-8.3 a/o Si being the primary alloy. In Phase 2, the amount of boron in ternary Ni-metalloid alloys was varied. In Phase 3, attempts to identify alternate substrates other than copper involved the use of Ni-metalloid as well as Ni-Fe-Cr-metalloid alloy melts.
