Special Issue on Environmental Effects on Additive Manufactured Alloys and Parts

Researchers and engineers presenting at ICAM 2022 in environmental effects on additively manufactured parts are invited to contribute to this Special Issue.

Additive manufacturing 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 environmental 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:

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

Articles for consideration in this special issue should be submitted here and should reference “ICAM 2022” in their cover letter.

Special Issue on Design and Modeling in AM

Utilizing the freedom of design enabled by techniques such as topology optimization and generative design approaches is one key success factor in making the most out of Additive Manufacturing. Design optimization, stress analysis, thermal modeling, microstructural evolution, and understanding the material-process-microstructure-property relationships significantly reduce the time and cost of AM implementation and improves adoption.

This special issue aims to provide the state of the art in terms of Design for Additive Manufacturing. Best papers related to areas on design and modeling from ASTM’s conference ICAM will be chosen and orchestrated for this special issue. The topics include, but are not limited to:

1. Design, modeling, and simulation methodologies in AM (such as those enabled by high-performance computing and machine learning)
2. Design for additive manufacturing, including processes and post-processing (Post-machining and heat treatment)
3. Topology optimization and reverse engineering (such as for legacy parts)
4. Optimization of AM designs and processes (Generative design, digital twins, CAE, etc.)
5. Development of AM material-process-microstructure-property relationships, prediction, and control of material properties
6. Standards needs for AM design and simulation
7. Case studies, industrial use-cases, and applications
8. Design of architected materials (Graded materials and cellular materials)

Fatigue and Fracture of Additively Manufactured Materials and Parts – 3rd Special Issue on Additive Manufacturing

Additive manufacturing (AM), which is a fabrication process through the repetitious deposition of material layers, provides unique opportunities to manufacture customized parts with complex geometries or functionally graded materials. Nevertheless, the fatigue behavior of AM parts is not yet fully understood, thus delaying the widespread adoption of this advanced manufacturing technology in a variety of industries such as aerospace, biomedical and automotive.

With the success of 1st and 2nd Special Issues, researchers and engineers presenting at ICAM 2022 in fatigue, fracture mechanics and materials science are invited to contribute to the 3rd Special Issue on Additive Manufacturing. Similarly, the aim of the 3rd special issue is to collect a series of articles related to all stages of fatigue failure including crack initiation, crack growth and final fracture of AM materials. The topics include, but are not limited to, experimental, analytical, and computational research on:

1. Fatigue and fracture behavior of AM materials
2. Effect of microstructure and defects on fatigue behavior
3. Development of new fatigue and fracture test methods
4. Failure mechanisms and crack formation in AM materials
5. Factors influencing the fatigue and fracture behavior (i.e. process/post-process, design parameters, residual stress, geometry, etc.)
6. Multiscale modeling of fatigue process (i.e. initiation, crack growth, etc.)
7. Fatigue and fracture analysis of functionally graded materials
8. Fatigue design for AM components and structures for different applications
9. Qualification, certification, and standardization of AM materials/parts for fatigue critical applications
