Twin-related grain boundary engineering of additively manufactured 316L stainless steel

December 1, 2025
Author(s)
Chenglu Tang, Jingfan Yang, Fan Zhang, Joseph Aroh, Ernest Porterfield, Barton Prorok, Xiaoyuan Lou
Twin-related grain boundary engineering (GBE) enhances the boundary-related degradation of materials, such as intergranular corrosion by incorporating a high density of twin boundaries. Conventional GBE typically requires one or multiple thermomechanical

Priming Additively Manufactured Cobalt-free Maraging Steels for Improved Properties via Changes to As-Built Microstructure

July 23, 2025
Author(s)
Alec Saville, Jake Benzing, Fan Zhang, Joseph Aroh, Jordan Weaver, Russell Evans, Nicholas Derimow, Samantha Webster, Nikolas Hrabe, Cassidy Allen, Newell Moser, May Martin, Jason Holm, Christin Aumayr, Tilman Seifert, Michael Hirtler
Supply chain challenges and health concerns have spurred the development of new Co-free, Cr-containing maraging steels with several new alloys already commercialized. These alloys are a less expensive and more sustainable form of the currently used Co

Personalized Medicine: A Quality by Design Approach to Printable Tablet Production

July 7, 2025
Author(s)
Thomas Forbes, Olivia Agolini, Zainab Altamimi, Jeffrey Lawrence
The versatility afforded by emerging additive manufacturing technologies (e.g., 3D printing and precision drop-on-demand deposition) has enabled the rapid and agile production of personalized medicine. The on-demand customization capabilities of these

Measurement of the three-dimensional shape and size distribution of 17 lunar regolith simulants: Simulant shape and size inter-comparison and simulant shape comparison with Apollo 11 and Apollo 14 lunar regolith

July 1, 2025
Author(s)
Edward Garboczi, Ann Debay, Orion Kafka, Newell Moser, Douglas Rickman, Ryan Wilkerson
Lunar regolith simulants are manufactured in order to provide a higher volume, much less expensive and more available source of material, compared to real lunar regolith material, upon which to test various instruments and machines that are being designed

Accurate keyhole instability prediction in metal additive manufacturing through machine learning-aided numerical simulation

June 3, 2025
Author(s)
Jiahui Zhang, Runbo Jiang, Kangming Li, Pengyu Chen, Xiao Shang, Zhiying Liu, Brian Simonds, Qianglong Wei, Hongze Wang, Jason Hattrick-Simpers, Tao Sun, Anthony Rollet, Yu Zou
A primary obstacle impeding the use of metal additive manufacturing technologies in fatigue-sensitive applications is the presence of porosity, primarily caused by keyhole instability. To tackle this challenge, it is imperative to accurately forecast

Tailored-Reflectivity Microstructures for Measuring Signal Sensitivity of Optical Coherence Tomography Medical Imaging Systems

May 25, 2025
Author(s)
Greta Babakhanova, Declan Fitzgerald, Joshua Guag, Zhuolin Liu, Daniel Hammer, Ryan Sochol, ANANT AGRAWAL
Optical coherence tomography (OCT) is a medical imaging technique which has transformed the practice of ophthalmology via high-resolution visualization and measurement of numerous ocular structures, the retina in particular. Despite its widespread use, the

A Fully Registered In-Situ and Ex-Situ Dataset for Metal Powder Bed Fusion Additive Manufacturing: Data Processing, Feature Extraction, Registration, and Uncertainties

May 8, 2025
Author(s)
Zhuo Yang, Yan Lu, Ho Yeung, Brandon Lane, Nicole Van Handel
This document details the data registration process for the previously published datasets from Additive Manufacturing Metrology Testbed (AMMT) parts, "Overhang Part X4," generated at the National Institute of Standards and Technology. The two datasets —one

Microstructural Features and Metastable Phase Formation in a High-Strength Aluminum Alloy Fabricated Using Additive Manufacturing

April 25, 2025
Author(s)
Andrew Iams, Jordan Weaver, Brandon Lane, Lucille Giannuzzi, Feng Yi, Darby LaPlant, John Martin, Fan Zhang
Additive manufacturing (AM) has captured recent attention for its potential to fabricate high-strength aluminum alloy components. A detailed understanding of the microstructure under the as-fabricated conditions is required to harness its potential. We

Insights on grain refinement of Al-Mn-Fe-Si alloy via in situ reaction during laser direct energy deposition

February 2, 2025
Author(s)
Qingyu Pan, Fan Zhang, Deepak Vikraman Pillai, Zilong Zhang, Yufeng Zheng, Lang Yuan, Monica Kapoor, John Carsley, Xiaoyuan Lou
In the present work, we studied the grain refinement by adding in situ reactants, pure titanium (Ti) or a combination of Ti and boron (B), and investigated the governing mechanism in Al-Mn-Fe-Si 3104 alloy made by laser direct energy deposition (DED)

Correlating Titanium Powder Manufacturing Methods and Resultant Particle Morphologies to Microstructural Properties, Particle Flight and Impact Velocity, and Bonding and Deposition Characteristics in Cold Spray Additive Manufacturing

January 23, 2025
Author(s)
Pranav Anumandla, Carlos Faggi, Sinan Muftu, Edward Garboczi, Newell Moser, Rachel Cook, Nicholas Derimow, Ozan Ozdemir
Unlike high temperature thermal spray processes and metal additive manufacturing methods that require extensive heat treatment, native particle microstructural properties in the feedstock powder have been shown to dictate the final thermomechanical

Surrogate modeling of microstructure prediction in additive manufacturing

November 21, 2024
Author(s)
Paul Witherell, Sankaran Mahadevan, Paromita Nath, Arulmurugan Senthilnathan
Variability in the additive manufacturing process and powder material properties affect the microstructure which influences the macro-scale material properties. Systematic quantification and propagation of this uncertainty require numerous process
