Additive Manufacturing of Steels and Stainless Steels

August 1, 2020
Author(s)
Carelyn E. Campbell, Mark R. Stoudt, Fan Zhang
This work briefly reviews the classification of the different types of steels, the most common AM processes used for steel and the available powder feedstock. The characteristics of the as-built microstructure, including porosity, inclusions and residual

Community Resilience-Focused Technical Investigation of the 2016 Lumberton, North Carolina Flood: An Interdisciplinary Approach

John W. van de Lindt, Walter G. Peacock, Judith Mitrani-Reiser, Nathanael Rosenheim, Derya Deniz, Maria Dillard, Tori Tomiczek, Andrew Graettinger, Patrick Crawford, Kenneth W. Harrison, Andre Barbosa, Jennifer Tobin, Jennifer Helgeson, Lori Peek, Mehrdad Memari, Elaina Sutley, Sara Hamideh, Donghwan Gu, Stephen Cauffman, Juan Fung
In early October 2016, Hurricane Matthew crossed North Carolina (NC) as a Category 1 storm, with some areas receiving 0.38 m to 0.46 m (15 to 18 in) of rainfall on already saturated soil. The National Institute of Standards and Technology (NIST) funded

Dominant factors for fracture at the micro-scale in electrodeposited nickel alloys

August 1, 2020
Author(s)
May L. Martin, Li-Anne Liew, David T. Read, Todd Christensen, Frank W. DelRio, John Geaney
Two different LIGA electrodeposited nickel alloys displayed distinct fracture modes after meso- scale tensile testing. The Ni-Co alloy failed in a ductile manner, while the Ni-Fe alloy failed in a more brittle-appearing manner. Various factors affecting

Early stage nucleation in barium disilicate glass

August 1, 2020
Author(s)
Ling Cai, Randall E. Youngman, David E. Baker, Aram Rezikyan, Minghui Zhang, Bryan Wheaton, Indrajit Dutta, Bruce G. Aitken, Andrew J. Allen
Early stage nucleation in silicate glasses is often evidenced by formation of nanosized regions that are stoichiometrically different from the surrounding matrix. The structural origin of these early stage nucleation sites is of great interest in gaining a

Numerical and Experimental Studies of Extinguishment of Cup-Burner Flames by C6F12O

August 1, 2020
Author(s)
Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok, Gregory T. Linteris
The extinguishment processes of cup-burner flames by adding a halon-replacement fire-extinguishing agent C6F12O (Novec 1230) to coflowing air in normal gravity have been studied computationally and experimentally. The time-dependent, axisymmetric numerical

The Antioxidant Vitamin E as a Membrane Raft Modulator: Tocopherols do not Abolish Lipid Domains

August 1, 2020
Author(s)
Mitchell DiPasquale, Michael H. Nguyen, Brett W. Rickeard, Nicole Cesca, Christopher Tannous, Stuart R. Castillo, John Katsaras, Elizabeth Kelley, Frederick A. Heberle, Drew Marquardt
A great deal of individuals across North America regularly supplement their diet with the antioxidant, vitamin E. This billion-dollar supplementation industry encourages the use of vitamin E with little evidence supporting its actual health benefits
