Special Issue Information

Dear Colleagues,

Phase transformations represent the most effective means of tailoring the microstructure and properties of engineering materials. Being generally defined as “a rearrangement of the atomic structure of the assembly”, phase transformations take place during melting, solidification, deformation, or heat treatment and include, for example, nucleation and growth, recovery and recrystallization, eutectoidal decomposition, precipitation from supersaturated solutions, deformation induced precipitation, deformation twinning, GP zone formation etc. Hence, understanding their fundamentals is critical for materials development, production, and application.

It is my pleasure to invite you to submit a manuscript to this Special Issue, which will focus on phase transformations in current and emerging structural metallic materials, critical for weight reduction. In addition to traditional magnesium, aluminium and titanium based alloys the issue will include novel lightweight high-entropy alloys that are also becoming candidates for substantial weight reduction. The scope will cover fundamental research, all aspects of alloy development, synthesis, heat treatment, component manufacturing, computer simulation and application related topics where phase transformations are considered.

Submissions of communications, full papers, and reviews are all welcome.

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.

Two common techniques of thermal analysis, Differential Scanning Calorimetry (DSC) and Cooling/Heating Curve Thermal Analysis (CCTA), based on different signal collected and utilizing samples with a weight difference of three orders of magnitude, were used to assess the solidification and melting behavior of Al-Ce binary alloys, containing from 5 to 20 wt. % Ce. Thermal analysis was accompanied by microscopic observations of solidified structures. For heating/cooling rates of 0.2–0.4 °C/s, temperatures of eutectic transformation L ↔ Al + Al11Ce3 in the Al-10Ce alloy along with additional proeutectic reactions L ↔ Al in the Al-5Ce hypoeutectic alloy and L ↔ Al11Ce3 in Al-15Ce and Al-20Ce hypereutectic alloys, were determined. Although there was a general agreement in major transformations, registered by DSC and CCTA during melting and solidification, differences in the reaction temperature determined exceeded the typical measurement errors for each technique. In addition, DSC and CCTA exhibited differences in detecting some proeutectic reactions and minor non-equilibrium effects, accompanying the eutectic transformation. Some factors that could contribute to differences observed and their implications for engineering practice were discussed. Full article
