Special Issue Information

Dear Colleagues,

The refractory world is changing as a result of the need to reduce carbon footprints and to support climate-positive industries. Advanced refractory materials based on functionalised metal–ceramic composites can help to fulfil the demand for smart refractory installations with increased lifetimes. In addition, the material design must satisfy circular economy needs.

In all cases, composites must withstand harsh environments in their application such as corrosion (contact with metallic and salt melts, reducing or oxidising atmospheres), thermal shock, thermal stresses and mechanical loads.

This Special Issue encourages authors to contribute works on topics including, but not limited to, the following:

  • Design and production of metal–ceramic composites used at temperatures above 1000 °C;
  • Functional properties, e.g., electrical and thermal conductivity, porosity, etc.;
  • Mechanical properties, e.g., characterisation of thermal shock behaviour, strength at RT and high temperature, etc.;
  • Oxidation or corrosion resistance of functional materials and/or composites.

Studies on any high-temperature material class, including classical ceramic refractories, refractory metal composites, and carbides (including MAX phases), are welcome for submission.

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. Metals 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 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 this study, the effect of adding different contents of yttrium (Y) during vacuum induction melting in Al2O3 and Y2O3 crucibles on the purification of DD5 alloys was investigated. The results show that the Y2O3 crucible exhibited great crucible stability and an excellent desulfurization effect when melting a Y-containing DD5 alloy. The S content of the alloy was reduced from 5.03 ppm to 1.36 ppm with the addition of 0.50 wt.% Y. Element Y combined with free S in the melt to form the YS phase, which was removed from the condensate shell and slag during the vacuum induction melting (VIM) process. Meanwhile, when the alloy was melted in the Y2O3 crucible with 0.50 wt.% Y addition, there was a reduction in S content from 2.77 ppm to 1.36 ppm compared to the Al2O3 crucible. Additionally, the loss of Y decreased from 0.12 wt.% to 0.05 wt.%. Full article
