Special Issue Information

Dear Colleagues,

We are delighted to announce that a Special Issue on “Novel Casting and Modelling Processes” will be published in Materials.

Innovations in casting processes and technology are changing the face of the casting industry. The improved understanding of liquid metal and solidification processes, the advances in computational power and casting simulation modelling tools, as well as the implementation of automation provide opportunities for tackling long-standing and new challenges. The present Special Issue aims to highlight the state of the art in research and technology related to metal casting, solidification and relevant simulations and modelling processes. Contributions may be related with (but not limited to) microstructure characterization and prediction for new and traditional alloys, casting defects elimination and structural integrity, properties and engineering performance of castings, metal melting, liquid metal flow and processing, rigging or methoding, process or product design and optimization. Furthermore, contributions related to improving sustainability and reducing the environmental impact of casting processes, energy and resource efficiency, additive manufacturing of moulds, patterns, cores and dies, recycling of metals and moulds, automation and digitalization of casting processes are particularly welcome.

In the present Special Issue, we invite contributions related to all novelty aspects of casting, solidification and modelling via regular research articles, short communications and reviews. We envision that this issue will contribute in promoting scientific and engineering advances in the field, underpinning future technological innovations in casting processes.

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. Materials is an international peer-reviewed open access semimonthly 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 2600 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.

In recent years, white chromium cast iron has gained a well-settled position among wear-resistant materials. In recent times, chromium cast iron samples containing titanium have attracted attention. In cast iron samples, titanium combines with carbon and forms TiC particles, which may be form a crystallization underlay for eutectic M7C3 carbides and austenite. Accordingly, the inoculation process occurring in the crystallizing alloy should result in the proper, regular distribution of fine eutectic chromium carbides in the austenitic matrix. The presented research was conducted on 20% Cr hypoeutectic white cast iron with the addition of 0.5, 1, and 2% of Ti. Ti inoculation and the presence of TiC allowed for superior wear properties to be obtained. However, the conducted study revealed a significant decrease in the impact strength of examined alloys, especially for the cast iron samples with a high amount of Ti, in which the TiC compounds agglomerated. Titanium compounds accumulate in clusters and their distribution is irregular. Most of the TiC compounds were transported by the crystallization front into the center of the castings, where micropores were formed, meaning they were no longer effective crystallization underlays. In the authors’ opinion, the agglomerate formation is strictly connected with the appearance of bifilm defects in the casting microstructure. The conducted research shows how an incorrect volume of an additive may have negative influences on the properties of the casting. This is a vital issue not only from a technological point of view, but also for economic reasons. Full article
