Special Issue Information

Dear Colleagues,

Aside from ultrahigh strength and elasticity, bulk metallic glasses possess plenty of favorable thermal, magnetic, and chemical properties. For this Special Issue in Metals, we aspire to publish a range of articles covering (i) glass formation kinetics, liquid fragility, and thermal forming, (ii) thermal annealing and nanocalorimetry, (iii) synchrotron X-ray radiation, (iv) hydrogen storage and conversion, (v) electro/photocatalytic/corrosion activity, (vi) influence of microalloying and nanocrystallization on magnetic/electrical behavior, (vii) biostability, cell interactions, and antimicrobial properties, (viii) finite element modeling and (ab initio) molecular dynamics simulations of synthesis, processing, and chemical activity, and (ix) additive manufacturing, (x) miscellaneous properties on different length-scales (acoustics, optics, thin-film coatings, powder processing, etc.) of metallic glasses and their composites. Although mechanical properties and electron microscopy studies are not the main focus, combinatorial studies with the aforementioned topics are also welcome.

For this Special Issue, we are looking forward to receiving regular research papers, reviews, and short communications.

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.

Abstract
The influence of isothermal annealing on the strain rate sensitivity (SRS) of a Zr-based bulk metallic glass (BMG) was investigated by nanoindentation. A more positive SRS is observed with a decrease in the content of the free volume (FV) of the sample. Furthermore, [...] Read more.
The influence of isothermal annealing on the strain rate sensitivity (SRS) of a Zr-based bulk metallic glass (BMG) was investigated by nanoindentation. A more positive SRS is observed with a decrease in the content of the free volume (FV) of the sample. Furthermore, the SRS becomes nearly constant with increasing annealing time when the FV is annealed out. By taking into consideration the FV-assisted activation and combination of the shear transformation zones (STZs), the underlying mechanism is well understood. The current work may offer useful insights into the correlation between the microstructure and mechanical properties of BMGs. Full article

In this work, the biomedical applicability and physical properties of magnesium-based metallic glass/polycaprolactone (PCL) composites are explored. The composites were fabricated via mechanical alloying and subsequent coextrusion. The coextrusion process was carried out at a temperature near to the supercooled liquid region of the metallic glass and the viscous region of the polymer. The structures, as well as thermal and mechanical properties of the obtained samples were characterized, and in vivo investigations were undertaken. The composite samples possess acceptable thermal and mechanical properties. Tensile tests indicate the ability of the composites to withstand more than 100% deformation. In vivo studies reveal that the composites are biologically compatible and could be promising for biomedical applications. Full article
