Special Issue Information

Dear Colleagues,

It is a great pleasure for me to invite you to submit a manuscript to the Special Issue "Synergy in bimetallic materials", which will be published in the journal Metals.

This Special Issue will be focused on interdisciplinary state-of-the-art research articles, communications, and reviews related to various aspects of the synthesis, characterization and application of bimetallic materials. The specific focus of the Special Issue is the synergy of the two metals in the bimetallic composition (alloy, nanoparticle, layered structure), because such non-additive interactions between the metals may result in a significant improvement of the properties of the bimetallic systems compared to the monometallic counterparts. Of special interest, of course, are nanomaterials, in as far as the synergetic effects are size-dependent and may be quite different depending on the morphology of the nanoparticles. One of the metals may affect the electronic state of the other metal causing electron transfer between the metals in the nanoparticles. Advanced architectures of bimetallic materials (core–shell, uniform or alloy particles, etc.) provide a driving force for the progress in diverse research areas and applications, including the development of new nano-engineered catalysts, smart materials, sensors, as well as materials for energy applications (harvesting, storage). This Special Issue will show the progress and reveal new aspects in the broad field of bimetallic (or in general polymetallic) materials. Combining individual contributions from these areas will allow us to produce a journal issue with a high impact. Thus, submissions focused on any materials and their novel applications that disclose new manifestations of the synergy of the components in bimetallic systems are cordially invited.

Please note that Metals is an open access journal, and the whole Special Issue will be freely available for all readers across the world. Information about open access options and conditions is provided on the journal website.

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.

To break through the limitation of fracture splitting process on material selection and solve problems during fracture splitting such as parts tearing, failing to split, dropping dregs, fracture surface deformation and so on, a new technique of setting natural splitting surface in casting blank is proposed, aiming to achieve brittle fracture along pre-set surface during fracture splitting process. In this research, casting blanks are produced with metal molds. A layer of AZ31 foil is set in advance before casting, the layer interacts with liquid LD10 aluminum alloy, forming a brittle interface layer across the whole casting, then a fracture splitting hole is machined in the middle of the casting blank and cracking grooves are machined on the inner hole near the interface to achieve fracture splitting. Experiment revealed that the initial crack on the specimen starts from the root of the cracking groove, and the crack basically expands along the pre-set fracture splitting surface. The fracture surface is characterized by flaky brittle fracture. There is residual magnesium and pellumina, which have characteristics of melt with low-melting point, and micro-porosity in the fracture. Further analysis suggests that the formation mechanism of a natural fracture splitting surface can be described as follows: the magnesium foil with strong oxidation in high-temperature alloy liquid interacts with the pellumina at the front of liquid flow, which forms a interface. Meanwhile a layer of melt with a low-melting point forming as a result of interface reaction is pushed to the edge of the grain boundary, and surface liquid film shrinks to be micro-porosity. With such a combined effect it finally forms the brittle surface, which provides the condition for conducting subsequent fracture splitting process. Full article
