Special Issue Information
Dear Colleagues,
As one of the most popular manufacturing processes for light metals such as aluminium and magnesium alloys in the casting industry, high-pressure die casting is known for its high productivity, high dimensional accuracy and excellent mechanical properties. However, due to the fierce turbulence and limited shrinkage feeding capability, defects such as entrapped air and shrinkage porosity can form in castings, which affects the stability of mechanical properties in the castings. Such variation in mechanical properties between Al-based or Mg-based alloys has been extensively researched and the main explanation comes down to the randomness in distribution of the above-mentioned defects in castings, which causes inhomogeneity in the cast microstructure and leads to early failure during the material deformation process. The formation and existence of potential defects in the HPDC process for light metals poses a huge threat to the alloy development, process design, as well as the manufacturing and application of HPDC products. In this Special Issue, the complete cycle of the HPDC process for light alloys will be addressed. Research areas of interest include, but are not limited to, the following areas from both experimental and modelling perspectives:
- Material selection/alloy development
- Microstructure and mechanical properties of the HPDC alloy
- HPDC machine selection and process design/optimization
- Melt flow, heat transfer, turbulence, intense shearing in HPDC
- Alloy nucleation, grain refinement, micro-segregation
- Solidification characteristics, defects formation mechanism, cast quality control
- Heat treatment and subsequent processing techniques
- Metal recycling and circulation
- Artificial intelligence, machine learning, big data analysis and ICME/material genome research work regarding the HPDC process

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
