Effect of Heating Rate and Grain Size on the Melting Behavior of the Alloy Nb-47 Mass% Ti in Pulse-Heating Experiments

September 1, 1998

D Basak, William J. Boettinger, Daniel Josell, Sam R. Coriell, J L. McClure, Sitaraman Krishnan, A Cezairliyan
The effect of heating rate and grain size on the melting behavior of Nb-47 mass % Ti is measured and modeled. The experimental method uses rapid resistive self-heating of wire specimens at rates between -10 2 and -10 4 K/s and simultaneous measurement of

Solute Trapping and Solute Drag in a Phase-Field Model of Rapid Solidification

September 1, 1998

N A. Ahmad, A A. Wheeler, William J. Boettinger, Geoffrey B. McFadden
During rapid solidification, solute may be incorporated into the solid phase at a concentration significantly different than that predicted by equilibrium thermodynamics. This process, known as solute trapping, leads to a progressive reduction in the

Multiple Similarity Solutions for Solidification and Melting

July 1, 1998

Sam R. Coriell, Geoffrey B. McFadden, R F. Sekerka, William J. Boettinger
We explore multiple one-dimensional similarity solutions during the solidification of a binary alloy and a pure material. The configuration is analogous that of a diffusion couple, for which multiple solutions in ternary alloys were discovered by Coates &
