Special Issue on Environmental Effects on Additive Manufactured Alloys and Parts

Researchers and engineers presenting at ICAM 2021 in environmental effects on additively manufactured parts are invited to contribute to this Special Issue.

Additive manufacturing (AM) has evolved over the years and research has primarily focused on the evaluation of microstructure characterization and mechanical performance with limited emphasis on environmentally induced degradation modes. Understanding environmental effects such as corrosion, decomposition, hydrogen embrittlement and stress corrosion cracking, on additively manufactured alloys is critical to enable use in structural components for engineering applications. Various studies have demonstrated significant differences in both microstructure and corrosion properties between AM alloys and conventionally processed alloys. It is also reported that post processing such as heat treatment, surface treatment, or coating may influence the performance of AM alloys against environment effects. On the characterization side, most studies have utilized legacy standards for corrosion  and environmental cracking testing. While the legacy standards may be applicable, further considerations may also be required.

The aim of this Special Issue is to collect a series of articles (both literature reviews and original research) related to all aspects of environmental impacts on AM parts. The topics include, but are not limited to:

  1. Quantification and characterization of corrosion in AM alloys
  2. Environmental cracking (e.g., HE, SCC, corrosion-fatigue) of AM alloys
  3. H-metal interactions in AM alloys
  4. Identification of AM specific environmental degradation modes
  5. Linking microstructure features to corrosion and environmental cracking properties
  6. Effects of processing (both build and post-processing) parameters on environmental degradation
  7. Methods to prolong life of AM parts against environment effects (e.g., surface enhancements)
  8. AM specific standardization/characterization issues and challenges
