Special Issue Information

Dear Colleagues,

Creep is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses. After a material creeps, its performance will deteriorate over time. High temperature is the trend of modern industrial development, and high efficiency (environmental extremes) and reliability (safety and long life) are a contradiction between the two aspects. In the field of transport and in the energy and chemical industries, creep is one of the main deformation mechanisms for the failure of components working under high stress or high temperature (e.g., aero-engines, solid metal batteries, nuclear reactors), which affects the safe and effective service of structural components. Hence, the study of creep-resistant materials is significant for industrial development. Due to the variety of metal materials, structures, and complex processes, it is difficult to form a unified creep resistance mechanism suitable for all metal materials. The creep behavior of various metal materials and the strengthening mechanisms have yet to be adequately studied. Further research on the creep resistance mechanism of metals is needed, and more creep resistance methods have yet to be explored. Developing new metal materials to meet various requirements will undoubtedly benefit industry development. For this Special Issue, we welcome the submission of original research articles, communications, and reviews on recent advances in the creep behavior of metallic materials, with a particular interest in the optimization of composition and microstructural design, the preparation of new creep-resistant metal materials, and the latest advances in creep experiments, characterization of microstructural evolution, and computational simulations at different scales.

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.

The creep properties of 15Kh2NMFAA nuclear WWER (water–water energetic reactor) vessel steel in the range of 500–1200 ∘C temperatures, which may appear during severe nuclear reactor accidents, were investigated. The present paper attempts to analyze the creep curves obtained from tensile testing at high temperatures using the Larson–Miller parametric technique. The power law rate and material coefficient of Norton’s equation with the Monkman–Grant relationship coefficient were found for each test temperature. It is shown that in accordance with the Monkman–Grant relationship coefficient values, changing the creep type from dislocation glide to high temperature dislocation climb occurs in the temperature range of 600–700 ∘C, which leads to a slope change in the Larson–Miller parameter plot and the conversion of steel creep behavior. It is also shown that in the range of A1–A3 temperatures, a stepwise change in creep characteristics occurs, which is associated with phase transformations. In addition, the constancy of the product of the time to rupture τr and the minimum creep rate ϵ˙min in the ranges of 600–700 ∘C and A3-1200 ∘C was noted. The proposed approach improves the accuracy of time to rupture estimation of 15Kh2NMFAA steel by at least one order of magnitude. Based on the research results, the calculated dependence of the steel’s long-term strength limit on temperature was obtained for several time bases, allowing us to increase the accuracy of material survivability prediction in the case of a severe accident at a nuclear reactor.
