Modelling of Solidification Microstructures

Materials Science Forum, 2000
This contribution briefly describes the modelling approaches that can be made for the prediction of microstructures during solidification processes. Due to the various scales involved in such processes, several methods must be considered. The phase-field method is capable of simulating the complex shape of dendrites and segregation pattern using a ...

Banded solidification microstructures

Metallurgical and Materials Transactions A, 1996
Banded microstructures are composed of alternate structures or phases which develop mostly parallel to the transformation front. At low growth velocities, bands of the same microstructure but with different scales form through periodic fluctuations of the solidification system.

Welding: Solidification and microstructure

JOM, 2003
Parameters that control the solidification of castings also control the solidification and microstructure of welds. However, various physical processes that occur due to the interaction of the heat source with the metal during welding add a new dimension to the understanding of the weld pool solidification.

Parametric control of microstructures in directional solidification

Physical Review A, 1992
We consider the effect of a periodic oscillation on the growth velocity of a liquid-solid interface during the directional solidification of a binary mixture. By using a different formalism for the description of the interface motion, we confirm the eventual stabilizing properties of the oscillation found in the analysis of Wheeler (J. Cryst. Growth 67,

Solidification microstructures: A conceptual approach

Acta Metallurgica et Materialia, 1994
Detailed theoretical models have been developed in the literature to correlate microstructural characteristics as a function of processing parameters. These results are examined with a broad perspective to show that various laws for microstructural transitions and microstructural spacings can be represented in terms of three simple characteristic ...

Equiaxed microstructure by rapid solidification

Materials Science and Engineering: A, 1991
Abstract Two stainless steel alloys with molybdenum and boron were rapidly solidified by laser melting or by melt spinning. According to the composition of the steel, two types of microstructure, either a columnar epitaxial structure or an equiaxed microcrystalline structure, were observed.

Nonequilibrium Solidification Microstructure in Alloys

1996
Different microstructural features derive from the solidification process, according to the thermal and thermodynamic parameters involved, which can exhibit the characteristics of metastable structures or at least of structures rarely observed in industrial processes involving solidification.

Computer Modeling of Solidification Microstructures

2004
Abstract Computational modeling assists in addressing the issues of solid/liquid interface dynamics at the microlevel. It also helps to visualize the grain length scale, fraction of phases, or even microstructure transitions through microstructure maps.
