Special Issue Information

Dear Colleagues,

This Special Issue focuses on Fatigue and Fracture of Additively Manufactured Materials that can bring together scientists and engineers working in the advanced manufacturing community to openly discuss the state-of-the-art, particularly with potential fatigue and/or fracture responses. It is well-known that such high-freedom fabricated advanced materials and components are necessarily obliged to key large-scale engineering complex structures subjected to complex environment and loading. This topic has been becoming a foundation of technical concern when pushing (hybrid) additive manufacturing processes into load-carrying structures. The depth understanding on damage evolution and modeling can help to qualify safety critical parts and further reduce the uncertainty of the physical system. Therefore, this Special Issue intends to collect contributions that address research studies related to theoretical, numerical and experimental investigations on the fatigue and fracture of advanced materials and structures using additive manufacturing. The Special Issue includes, but is not limited to, the following topics:

  1. Fatigue crack initiation and propagation from defects;
  2. Low- and high-cycle fatigue performance;
  3. Modeling process-microstructure-property-performance;
  4. Damage tolerance approach based on long cracks;
  5. Uncertainty analysis due to defects, roughness and residual stress;
  6. Machine-learned health prognosis and in situ monitoring;
  7. Stepwise fatigue assessment framework.

Manuscripts should be submitted online at 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.

This study investigates the very-high-cycle fatigue (VHCF) behavior at elevated temperature (650 °C) of the Inconel 718 alloy fabricated by selective laser melting (SLM). The results are compared with those of the wrought alloy. Large columnar grain with a cellular structure in the grain interior and Laves/δ phases precipitated along the grain boundaries were exhibited in the SLM alloy, while fine equiaxed grains were present in the wrought alloy. The elevated temperature had a minor effect on the fatigue resistance in the regime below 108 cycles for the SLM alloy but significantly reduced the fatigue strength in the VHCF regime above 108 cycles. Both the SLM and wrought specimens exhibited similar fatigue resistance in the fatigue life regime of fewer than 107–108 cycles at elevated temperature, and the surface initiation mechanism was dominant in both alloys. In a VHCF regime above 107–108 cycles at elevated temperature, the wrought material exhibited slightly better fatigue resistance than the SLM alloy. All fatigue cracks are initiated from the internal defects or the microstructure discontinuities. The precipitation of Laves and δ phases is examined after fatigue tests at high temperatures, and the effect of microstructure on the formation and the propagation of the microstructural small cracks is also discussed.
