Thermoelectric magnetohydrodynamic effects on solidification of metallic alloys in the dendritic regime
TL;DR: In this paper, the Seebeck and Peltier effects have been investigated on the liquid-solid interface of binary alloys with different thermoelectric powers and their influence on the solidification process.
Survey of Research into Electromagnetic and Other Wave Effects on Mechanical Behavior and Processing of Materials
George Mayer,Benjamin Tao +1 more
TL;DR: In this article, a survey was conducted for the period 1960-1990 of the open literature sources with special focus on electromagnetic and other wave phenomena, and the statistics and trends in activity have been examined in four main areas: electric fields and currents, ultrasonics, microwaves, and magnetic fields.

The effect of an electric current on rod-eutectic solidification in Sn-0.9 wt.% Cu alloys
TL;DR: In this paper, a model for the directional growth of the eutectic in the presence of an electric current was presented, and it was used to illustrate that electromigration is not important in affecting changes in spacings for steady EUTectic growth conditions.

Electrical field freezing effect on laser floating zone (LFZ)-grown Bi2Sr2Ca2Cu4O11 superconducting fibres
TL;DR: In this paper, an electrical assisted laser floating zone (EALFZ) solidification process makes the tailoring of fiber microstructures possible, and the application of a dc electrical current of during the solidization process of Bi2Sr2Ca2Cu4O11 nominal composition fibres strongly modified phase development, crystal shapes and effective distribution coefficients.

Stability of a Planar Interface During Solidification of a Dilute Binary Alloy
W. W. Mullins,R. F. Sekerka +1 more
TL;DR: In this article, the stability of a moving planar liquid-solid interface during unidirectional freezing of a dilute binary alloy is theoretically investigated by calculating the time dependence of the amplitude of a sinusoidal perturbation of infinitesimal amplitude introduced into the planar shape.

A nonlinear stability analysis of the freezing of a dilute binary alloy
David J. Wollkind,L. A. Segel +1 more
TL;DR: In this paper, a nonlinear model is used to describe an experimental situation in which solidification is controlled so that the mean position of the interface moves with constant speed, and it is found that the interface can be unstable to finite amplitude disturbances even when linear stability theory predicts stability to infinitesimal disturbances.
