Numerical Modeling of Heat Transfer and Microstructure Evolution of Alloys

Dear Colleagues,

Metallic alloys such as castings of aluminum alloys are widely used in aerospace and automobile industries as well as civil engineering applications due to their desirable strength-to-weight ratio, good resistance to corrosion, and relatively low raw material cost. However, solidification microstructures and microporosity defects are important factors impacting the mechanical properties of materials.

The evolution and formation of microporosity defects are strongly associated with the evolution of dendritic/eutectic growth during alloy solidification. Understanding bubble evolution during solidification can help in obtaining the desired microstructure and, hence, high-quality castings.

The aim of this Special Issue is to publish papers that improve our understanding of the mechanism of solidification microstructure evolution and microporosity formation, as well as those intensively investigating their interaction utilizing numerical simulations and in situ observation experiments of directional solidification in This topic has important academic and practical significance for improving the understanding of the underlying physics of solidification, guiding alloy design, optimizing process parameters, controlling microstructures and predicting microporosity defects.

Numerical simulations have yielded many important results in the study of solidification structure evolution and multiphase fluid flow, bridging the limitations of experimental and theoretical studies and providing an effective research approach for further investigation in the fields of solidification science and fluid flow by investigating phase-change kinetics, thermodynamic calculations, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
