Special Issue Information

Dear Colleagues,

As the Second Law of Thermodynamics suggests, failure is an intrinsic characteristic of any materials system. Given its prevalence, one would assume that assessing a materials system’s capability to endure is relatively straightforward; however, this is not the case. The proverbial butterfly effect is an appropriate moniker for failure as delicate and pernicious events rooted in the lower-length scales can evolve almost unpredictably to severely compromise the structural integrity of a materials system. For example, in metallic systems, seemingly innocuous dislocations at the atomic scale can evolve into life-limiting cracks in a myriad of ways. Some dislocations might nucleate microcracks whose stress intensities are amplified by micron-sized voids, thereby facilitating ductile crack propagation. Others might initiate microcracks that evolve synergistically with oxidation, creep, and/or fatigue loading. In organic materials systems, physiological processes, such as the up-regulation of proteins (e.g., in cell membrane repair), can act to strengthen or even heal the system, making the question of failure both stochastic and highly non-linear.

This Special Issue is intended to give material scientists, experimentalists, computational mechanicians, biochemists, applied mathematicians, and stakeholders, such as fleet managers, a platform to disseminate their novel work at the intersection of fundamental failure-related science and more practical life-ing technologies. Materials systems of interest include, e.g., metals and their alloys, metallic glasses, metal matrix composites, functionally graded materials, ceramics and ceramic composites, and organic materials, such as biofilms and bone. This breadth of systems is meant localize competencies from different fields that typically do not overlap with one another, thereby presenting opportunities for cross-cutting innovation. Work in experimental methods development (e.g., in situ fracture tests, tests for mixed-mode fracture, novel approach for uncertainty propagation while forecasting life) and computational analysis (e.g., finite element framework bridging scales, application of damage mechanics or geometrically explicit crack growth, cumulative damage modeling) is requested.

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 2300 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.

Nickel base superalloys are widely used to manufacture turbine blades, and overheating poses a serious threat to the safe service of turbine blades. In this study, a second-generation nickel base single crystal superalloy was taken as the research object, and we carried out the overheating treatment at 1100 °C and 1300 °C, and then tested the creep properties at 1000 °C/300 MPa and 1100 °C/130 MPa. Through systematic analysis of creep properties, γ/γ’ phases, and creep voids, the effects of overheating on the microstructures and creep properties of the experimental superalloy were revealed. The results demonstrate that the effect of overheating at 1100 °C on the microstructure of the experimental superalloy can be ignored, and the effect on the creep property is limited. The degree of γ’ dissolution is gradually increased and the creep property is reduced with overheating time extending at the overheating temperature of 1300 °C. Full article
