OnDemand Webinar Series


Additive Manufacturing of Metals: Complex Microstructures and Architecture Design


Sep 17, 2020 10:00am ‐ Sep 17, 2020 11:30am

Free

Description

This webinar was presented in conjunction with the August, 2020 Journal of Materials Research Focus Issue on this topic, and it featured four talks from experts in the field, followed by live Q&A sessions with each.

Additive manufacturing (AM) is a disruptive technology, not only because it enables the production of components with complex geometries, but also because it provides unique opportunities for microstructure control and materials design. In contrast to conventional manufacturing technologies,such as casting, forging, and hot rolling, AM offers additional degrees of freedom to “architect” the material microstructure across many length scales. Owing to this unique capability, both beam-based processes—such as power bed fusion (PBF) and directed energy deposition (DED)—as well as non-beam-based processes—such as cold spray, additive friction stir deposition, and ultrasonic additive manufacturing—unlock new opportunities for tailoring mechanical and functional properties of metals and alloys. 

In this webinar and associated JMR Focus Issue, we highlight research on the microstructures resulting from different AM processes and their impact on the mechanical and physical properties of metallic materials. The issue includes both experimental and modeling works focusing on different materials systems, such as steels, aluminum-,titanium-, and nickel-base alloys, refractory metals, and high entropy alloys. We have also captured a portion of the broad spectrum of research in AM, from finite element simulations and topology optimization to microstructure characterization and mechanical testing. Many new tools, such as machine learning methods, have become powerful for AM.
