Special Issue Information

Dear Colleagues,

You are invited to contribute to this upcoming Special Issue of Coatings entitled “Latest Insights in Metal Fatigue, Failure, and Fracture”. This Special Issue will encompass the latest research on the topics of metal fatigue, structural failures, and material fractures.

Fatigue in materials represents one of the most prevalent causes of failure in modern constructions. The goal of engineers and scientists is to eliminate fatigue or successfully manage it to ensure the reliability of analysed structures. Based on fatigue tests and the simulation of metal components, the theory and method of fatigue damage assessments of metal materials or components are proposed. These methods provide a base for structural safety, as well as for the design, material selection, and process selection of metal components. This research requires multidisciplinary expertise, including material science, structural analysis, detection technology, structural design, manufacturing technology, computer technology, quality assessment, physics, reliability, etc. In order to solve the complex engineering fatigue problem, it is necessary to involve both micro- and macro-scale theory and experimental methods.

Metal fatigue, failure, and fracture is a very broad and diverse field, encompassing the analysis of concepts such as residual strength or life, crack propagation, damage assessment using different fatigue damage detection methods, and various related topics.

We look forward to your contributions to this Special Issue.

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. Coatings 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.

AISI 4340 is a medium-carbon low-alloy steel that has gained distinctive attention due to its advanced properties including high strength, high toughness, and heat resistance. This has led to its commercial usage in a wide variety of industries such as construction, automotive, and aerospace. AISI 4340 is usually machined in a hardened state through a hard-turning process, which results in high heat generation, accelerated tool wear, low productivity, and poor surface quality. The application of high-speed machining helps improve the material removal rate and surface finish quality, yet the elevated temperature at the cutting zone still poses problems to the tool’s lifespan. Apart from using advanced cutting tool materials, which is costly, researchers have also explored various cooling methods to tackle the heat problem. This paper presents a review of a sustainable cooling method known as minimum quantity lubrication (MQL) for its application in the high-speed turning of AISI 4340 steel. This study is centered on high-speed turning and the application of MQL systems in machining AISI 4340 steel. It has been observed that the hard part turning of materials with a hardness exceeding 45 HRC offers advantages such as improved accuracy and tighter tolerances compared to traditional grinding methods. However, this process leads to increased temperatures, and MQL proves to be a viable alternative to dry conditions. Challenges in optimizing MQL performance include fluid penetration and lubrication effectiveness. Full article
