400-Fold Reduction in Saturation Field by Interlayering
Topic: Metals
Published: 1/13/2009
Authors: William F. Egelhoff Jr., John E Bonevich, Philip Pong, John Unguris, Robert D McMichael, Gery R Stafford, Carlos R Beauchamp
Abstract: The buildup of stress with increasing thickness of magnetic thin films is a common phenomenon that often induces undesirable saturation fields that can convert an otherwise magnetically soft film into a magnetically hard one. We have found that by i

A Study of the Fundamental Relationships Between Deformation-Induced Surface Roughness and Strain Localization in AA5754
Topic: Metals
Published: 7/1/2009
Authors: Mark R Stoudt, Joseph Bunton Hubbard, Mark A Iadicola, Stephen W Banovic
Abstract: This research characterizes deformation-induced surface roughness produced by 3, in plane, proportional strain modes to determine the microstructural conditions that promote strain localization in AA5754-O aluminum alloy sheet. Integrating high-reso

ADVANCED NON-DESTRUCTIVE HYDROGEN SENSORS TO PREVENT MATERIAL DEGRADATION FROM HYDROGEN DAMAGE
Topic: Metals
Published: 1/5/2009
Authors: Angelique N Lasseigne, Kamalu Koenig, David Olson, Brajendra Mishra, Joshua Jackson, Thomas Allen Siewert, Joseph David McColskey
Abstract: New higher strength pipeline steels (X100 and X120) exhibit lower tolerance for hydrogen (diffusible and formed hydrides) before
significant degradation or failure occurs. It is essential to have advanced sensors to monitor the hydrogen content and

Analysis of Welding Parameter Distribution in Stud Arc Welding
Topic: Metals
Published: 7/15/2007
Authors: Ivan Samardzic, Stefanija Klaric, Thomas Allen Siewert
Abstract: This paper describes the application of on-line monitoring system for recording welding current and voltage during stud arc welding with a ceramic ferrule. Recorded values of welding current and voltage are analyzed off-line for the weld process wi

Analyzing Microstructure by Rietveld Refinement
Topic: Metals
Published: 6/1/2005
Authors: Davor Balzar, N C Popa
Abstract: Rietveld refinement has a primary purpose of refining crystal structure. However, this powerful technique is being increasingly used for obtaining microstructural information, such as texture, crystallite size, strain and stress, and crystalline defe

Boundary Effects on the Determination of the Effective Parameters of a Metamaterial from Normal Incidence Reflection and Transmission
Topic: Metals
Published: 6/1/2011
Authors: Sung Kim, Edward E. Kuester, Christopher L Holloway, James R. Baker-Jarvis, Aaron D. Scher
Abstract: This paper presents a method for the determination of the effective electromagnetic parameters of a metamaterial, taking boundary effects at the interfaces between a conventional material and metamaterial into account. In the technique presented here

CTOA Measurements of Welds in X100 Pipeline Steel
Topic: Metals
Published: 10/3/2008
Authors: Elizabeth S Drexler, Philippe P. Darcis, Christopher N McCowan, John Matthew Treinen, Avigdor Shtechman, Roni Reuven, Thomas Allen Siewert, Robert Smith, J. Merritt, Joseph David McColskey
Abstract: A suite of tests characterizing X100 pipeline steels was initiated at the National Institute of Standards and Technology (NIST) in Boulder. Part of the test matrix included testing the toughness of the base metal, welds, and heat-affected zones (HAZ

Cold Neutron Activation Analysis, a Nondestructive Technique for Hydrogen Level Assessment in Zirconium Alloys
Topic: Metals
Published: 6/1/2012
Authors: Rick L Paul, Adrien Couet, Arthur Motta, Robert Comstock
Abstract: We propose a novel use of a non-destructive technique to quantitatively assess hydrogen concentration in zirconium alloys. The technique, called Cold Neutron Prompt Gamma Activation Analysis (CNPGAA), is based on measuring prompt gamma rays following
