Building an In-Space Circular Economy - Seminar Series Report

September 29, 2026
Author(s)
Andrew Iams, Kelsea Schumacher, Jon Beam, Carolyn Pace, Dianne Poster
Traditional space activities have followed a linear, single-mission model in which spacecraft are designed, launched, operated, and ultimately disposed of through atmospheric reentry or relocation to graveyard orbits. As the commercial space sector grows

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

Enhanced localized corrosion resistance of Ni-based alloy 625 processed by directed energy deposition additive manufacturing

April 15, 2024
Author(s)
Karthikeyan Hariharan, Andrew Iams, James Zuback, Todd Palmer, Narasi Sridhar, Rashed Alazemi, Gerald Frankel, Eric Schindelholz
We report a significant improvement in localized corrosion resistance of Ni-based alloy 625 processed by directed energy deposition (DED) in an aggressive aqueous chloride environment. Disparities observed in the polarization behavior between DED and
