Cross-Scale Modeling of Metallic Materials on Creep and Fatigue Performance

Dear Colleagues,

The creep and fatigue performance of metallic materials under harsh environments such as high temperatures and high stress is a core factor determining the service life and reliability of equipment in critical sectors such as aerospace and energy power. The degradation and failure of these macroscopic properties originate from the irreversible evolution of the material's internal microstructure (e.g., dislocations, grain boundaries, precipitates) under the coupled effects of load and time. Traditional empirical or semi-empirical models have limited extrapolation capability and struggle to reveal the underlying physics or achieve accurate life prediction. Consequently, developing cross-scale modeling methods capable of bridging microscopic mechanisms and macroscopic behavior has become a forefront and core challenge in this field.

In this Special Issue, we welcome research on cross-scale modeling bridging the vast spatial and temporal scales ranging from the atomic and micro levels to the macro level. Research detailing rntegration with artificial intelligence is also of great interest.

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 250 words) can be sent to the Editorial Office for assessment.

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.
