Prediction of Dendrite Growth Velocity in Undercooled Binary Alloys Based on Transfer Learning and Molecular Dynamics Simulation

Crystals
The growth velocity of the crystal–melt interface during solidification is one of the important parameters that determine the crystal growth morphology.

Evidence for an extensive, undercooling-mediated transition in growth orientation, and novel dendritic seaweed microstructures in Cu-8.9 wt.% Ni

, 2013
Within the context of rapid solidification, a melt-fluxing technique has been employed to study the microstructural development and the velocity–undercooling relationship of a Cu–8.9 wt.% Ni alloy. A number of microstructural transitions have been observed

A Study of Undercooling Behavior Of Immiscible Metal Alloys in the Absence of Crucible-Induced Nucleation [PDF]

, 1998
The purpose of this study is to investigate the question: Would eliminating the crucible eliminate the wall-induced nucleation of one of the liquid phases in an immiscible alloy and result in undercooling of the liquid into the metastable region thereby ...

On the composition dependence of undercooling in binary alloy melts

, 1990
The driving free energy for nucleation of a primary solid phase from an undercooled liquid solution is an important parameter in the theory of nucleation. In the present study an expression for the driving free energy has been obtained in a form that can

The alloy undercooling experiment on the Columbia STA 61-C space shuttle mission [PDF]

, 1987
An Alloy Undercooling experiment was performed in an electromagnetic levitator during the Columbia STS 61-C mission in January 1986. One eutectic nickel-tin alloy specimen was partially processed before an equipment failure terminated the experiment ...

Semi-quantitative model of the microstructure development in the high-alloyed iron based alloy during atomization

Materials Research, 2012
The paper deals with the analysis of microstructure formation in the tool steel of ledeburite type Ch12MF4 with the chemical composition of 2.37% C, 12.06% Cr, 1.2% Mo and 4.0 % V [wt. (%)] in the process of nitrogen gas atomization.
