Permeability Measurements of 3D Microstructures Generated by Phase Field Simulation of the Solidification of an Al-Si Alloy during Chill Casting
Autor: Ralf Berger, Markus Apel, Gottfried Laschet, Wilhelm Jessen, Wolfgang Schröder, Jens Wipperfürth, Johannes Austermann, Christian Hopmann
Publikováno v: Metals, Vol 11, Iss 12, p 1895 (2021)
The permeability of the semi-solid state is important for the compensation of volume shrinkage during solidification, since insufficient melt feeding can cause casting defects such as hot cracks or pores. Direct measurement of permeability during the

Towards a metadata scheme for the description of materials – the description of microstructures
Autor: Georg J. Schmitz, Bernd Böttger, Markus Apel, Janin Eiken, Gottfried Laschet, Ralph Altenfeld, Ralf Berger, Guillaume Boussinot, Alexandre Viardin
Publikováno v: Science and Technology of Advanced Materials, Vol 17, Iss 1, Pp 410-430 (2016)
The property of any material is essentially determined by its microstructure. Numerical models are increasingly the focus of modern engineering as helpful tools for tailoring and optimization of custom-designed microstructures by suitable processing

Micro-macro Coupled Solidification Simulations of a Sr-Modified Al-Si-Mg Alloy in Permanent Mould Casting
Autor: Bei Zhou, Janin Eiken, Nino Wolff, Herfried Behnken, Gottfried Laschet, Markus Apel
Publikováno v: Lecture Notes in Mechanical Engineering ISBN: 9783030703318
Casting simulations incorporating solidification models are commonly applied to improve the dimensional accuracy of casting components. Challenging for a predictive casting simulation is the precise description of the solidification process of the ca

Evaluation and Transport of the Crystallization Heat in an Iterative Self-consistent Multi-scale Simulation of Semi-crystalline Thermoplastics
Autor: Jonathan Alms, Gottfried Laschet, Christian Hopmann
Publikováno v: Lecture Notes in Mechanical Engineering ISBN: 9783030703318
In the injection molding process of semi-crystalline thermoplastics, the melt is subjected to a complex deformation and temperature history. This leads to an inhomogeneous microstructure over the component and thus to local inhomogeneities in the com
