Advances in Testing and Predictive Modelling of Failure in Heat Resistant Steels

Dear Colleagues,

Heat resistant steels have wide ranging elevated temperature applications in the power generation, aero, petrochemical and incineration industries. Many components require periodic replacement due to a variety of factors such as safety, deterioration, efficiency, aging and costs. The causes for failure extend to creep, fatigue and oxidation/corrosion or a combination of these processes. Improvements in composition, fabrication and material properties can only be verified by a length process of testing and validation against specific operating conditions. With alloy costs rising significantly over the past few years, increasing the useful life of these components can dramatically reduce maintenance costs. It is possible to accelerate the new or improved alloy development process and also extend the life and improve safety and the structural integrity of the components through a combination of optimised fabrication, material selection, design, operation, laboratory testing, feature testing combined with new numerical modelling and virtual testing methods. This Special Issue will highlight the most important recent advances in the aforementioned areas focusing on fabrication, testing and predictive numerical modelling and damage and defect assessment of laboratory tests of heat resistant steels, as well as for components operating at elevated temperatures.

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.
