Special Issue Information
Dear Colleagues,
Amorphous alloys are special materials without long-range order and with high strength, and often exhibit higher ductility than covalent glasses due to their versatile metallic bonds. These alloys came into the focus of materials research because their ductility at ambient temperature screened by a plastic instability process, which leads to fracture via formation of intense shear bands. Deformation methods with mechanical constraints, including nanoindentation, bending, torsion, or high-pressure torsion (HPT), reveal inherent plasticity and highlight the role of internal stresses and atomic rearrangements in shear-band formation. Measuring or predicting internal stresses and related atomic processes in amorphous structures are still not a routine procedure. At the same time, deformation-controlled defect formation in amorphous alloys has potentially many significant advantages over traditional thermal treatments providing special microstructural features, such as ductile glasses, low temperature H-storage, and sharp nanofeatures.
In this Special Issue, both experimental and theoretical results on deformation-induced behaviour in various amorphous alloys and metallic glasses are targeted. Especially, works discussing shear banding, deformation-induced structural changes, internal stresses, and related atomic processes are highlighted.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers and communications are 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. Materials is an international peer-reviewed open access semimonthly 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.
