The modern understanding of metal plasticity and fracturing began in the 1920s with the pioneering work, first, on crack-induced fracturing by Griffith and, secondly, on dislocation-enhanced crystal plasticity by Taylor, Orowan, and Polanyi. Modern counterparts of this work are fracture mechanics as invented by Irwin and dislocation mechanics initiated in large part by Cottrell. No less important was the breakthrough development of optical characterization of sectioned polycrystalline metal microstructures begun by Sorby in the late 19th century, leading eventually to modern x-ray and electron microscopy methods of assessing crystal fracture surfaces, via fractography, and internal dislocation behaviors. A major current effort is to match computational simulations of metal deformation/fracturing behaviors with experimental measurements made over extended ranges of metal microstructures and over varying external conditions of stress-state, temperature, and loading rate. The relationship between such simulations and the development of constitutive equations for a hoped-for predictive description of material deformation/fracturing behaviors is an active topic of research. The purpose of the present Special Issue is to offer a publication venue for current reports on the two subjects of understanding metal failures and understanding corresponding deformation strengths relating to metal processing.

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 1500 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.
