Columnar and equiaxed solidification in a microgravity environment ? The CETSOL project
(2017)The formation of the microstructure and the grain structure during solidification is affected by buoyancy-driven flow and movement of crystals growing in the melt. To allow for pure diffusive solidification conditions, ... -
Columnar to Equiaxed Transition in Peritectic TiAl Based Alloy Studied by a Power-Down Technique

Conditions for CET in a gamma TiAl alloy
(2015)The solidification of gamma TiAl alloys is of interest to the aerospace and automotive industries. A gamma TiAl multicomponent alloy: Ti–45.5Al–4.7Nb–0.2C–0.2B (at. %) has been the focus of a study to investigate the ... -
An experimental-numerical method for estimating heat transfer in a Bridgman furnace
(2014)Direct measurement of heat flux and heat transfer coefficients in a Bridgman furnace is not always possible using traditional methods. This study characterised a vertical tubular Bridgman furnace using experimental data ... -
A Front Tracking Model for Transient Solidification of Al-7wt%Si in a Bridgman Furnace
(2012)The Bridgman furnace is widely used in industry and research. This paper outlines a working onedimensional model for tracking the columnar solidification front in a Bridgman furnace where the pulling velocity, and hence ... -
Macroscale modelling of Bridgman furnace solidification for the prediction of texture evolution and columnar to equiaxed transition
(Institute of Physics, 2016)Bridgman furnaces are commonly used in solidification research owing to their convenience when setting the desired solidification parameters, specifically, the nominal temperature gradient and nominal growth rate. The work ... -
Theoretical analysis to interpret projected image data from in-situ 3-dimensional equiaxed nucleation and growth
(2017)In-situ observation of crystal growth in transparent media allows us to observe solidification phase change in real-time. These systems are analogous to opaque systems such as metals. The interpretation of transient ...
