Phase Composition and Phase Transformation of Additively Manufactured Nickel Alloy 718 AM Bench Artifacts

February 5, 2024
Author(s)
Fan Zhang, Aaron Johnston-Peck, Lyle E. Levine, Michael Katz, Kil-Won Moon, Maureen E. Williams, Sandra W. Young, Andrew J. Allen, Olaf Borkiewicz, Jan Ilavsky
Additive Manufacturing (AM) technologies offer unprecedented design flexibility but are limited by a lack of understanding of the material microstructure formed under their extreme and transient processing conditions and its subsequent transformation

Location-specific Microstructure Characterization Within IN625 Additive Manufacturing Benchmark Test Artifacts

March 3, 2020
Author(s)
Mark R. Stoudt, Maureen E. Williams, Lyle E. Levine, Adam Abel Creuziger, Sandra A. Young, Jarred C. Heigel, Brandon Lane, Thien Q. Phan
Additive manufacturing (AM) of metals creates segregated microstructures with significant differences from those of traditional wrought alloys. Understanding how the local build conditions generate specific microstructures is essential for developing post

Phase Fraction and Evolution of Additively Manufactured 15-5 Stainless Steel and Inconel 625 AM- Benchmark Artifacts

August 5, 2019
Author(s)
Fan Zhang, Lyle E. Levine, Andrew J. Allen, Sandra A. Young, Maureen E. Williams, Mark R. Stoudt, Kil-Won Moon, Jarred C. Heigel, Jan Ilavsky
A proper understanding of the structure and microstructure of additive manufactured (AM) alloys is essential not only to the prediction and assessment of their material properties, but also to the validation and verification of computer models essential to

Interim Report on the Examination of Corrosion Damage in Homes Constructed with Imported Wallboard: Examination of Samples Received September 28, 2009

June 30, 2010
Author(s)
David J. Pitchure, Richard E. Ricker, Maureen E. Williams, Sandra W. Claggett
Since many household systems are fabricated with metallic materials, changes to the household environment that accelerate corrosion will increase the failure rates of these systems. Recently, increased failure rates have been reported in homes constructed
