Predicting the columnar-to-equiaxed transition for a distribution of nucleation undercoolings
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
A deterministic mathematical model for steady-state unidirectional solidification is proposed to predict the columnar-to-equiaxed transition. In the model, which is an extension to the classic model proposed by Hunt [Hunt ...
Unidirectional Solidified Zn-Al-Si-Cu Alloys: Columnar-to-Equiaxed Transition (CET)
(IJEIT, 2014-03)
The present investigation was undertaken to investigate the directional solidification of Zinc-Aluminum alloys with addition of Silicon and Copper, specifically Zn-20%Al-10%Si-3%Cu alloys (weight percent) under different ...
Experimental analysis of corrosion resistance on columnar to equiaxed transition region of as cast structures of Al-Cu alloys

An experimental investigation of the columnar-to-equiaxed grain transition in aluminumcopper hypoeutectic and eutectic alloys
(Elsevier Science, 2010-07-24)
Providing benchmark data of the thermal and metallographic parameters during the columnar-to-equiaxed transition (CET) in a wide range of alloy concentrations is of fundamental importance for understanding this phenomenon ...
Macrostructural and microstructural development in Al-Si alloys directionally solidified under unsteady-state conditions

Columnar-to-Equiaxed Transition in Metal-Matrix Composites Reinforced with Silicon Carbide Particles
(Hindawi Corporation, 2013-12)
The present work is focused on the study of the effect of directional heat extraction on the silicon-carbide (SiC) distribution in zinc-aluminum matrix composites (MMCs) and on the columnar-to-equiaxed (CET) position in ...
Deterministic mathematical model for the prediction of the as-cast macrostructure
(ESCOLA DE MINAS, 2008)
A multiphase deterministic mathematical model was implemented to predict the formation of the grain macrostructure during unidirectional solidification. The model consists of macroscopic equations of energy, mass, and ...
Mechanical Blocking Mechanism for the Columnar to Equiaxed Transition
(SPRINGER, 2008)
Mechanical blocking of the columnar front during the columnar to equiaxed transition (CET) is studied by quantitatively comparing the CET positions obtained with one stochastic model and two deterministic models for the ...
