One of the most striking properties of glass-forming liquids is their dynamical properties, such as viscosity, diffusion coefficient, and structural relaxation time. Within a few hundred degrees change in temperature, these properties change by twelve to fourteen orders of magnitude in a highly non-linear manner. In particular, liquids can be classified based on their dynamical properties by their “fragility”. This is defined by the logarithmic rate of change of their properties on a reduced temperature scale, T(subscript g)/T, where T(subscript g) is the glass transition temperature. Liquids with smaller magnitudes of this parameter are called “strong”, and those with larger magnitudes are known as “fragile”. Among other properties, this parameter plays an important role in glass formation.
Although a great deal of effort has been made to understand the dynamical properties of metastable (below the equilibrium melting temperature) supercooled liquids, much less has been done to understand their high temperature properties. Recently, a significant body of theoretical and experimental work, especially on metallic liquids, has focused on this topic. This Special Issue of Metals, entitled “Recent Progress in High Temperature Dynamical Properties and Fragility in Metallic Liquids”, aims to highlight recent developments in this field. We cordially invite submissions related to this topic from experimental, theoretical, and computer simulation groups.

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 papers will be 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 1600 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.
