The Effect of Pb Contamination on the Solidification Behavior of Sn-Bi Solders

January 1, 2001
Author(s)
Kil-Won Moon, William J. Boettinger, Ursula R. Kattner, C A. Handwerker, D J. Lee
This paper presents experimental results and theoretical calculations to evaluate the effects of Pb contamination on the solidification behavior of Sn-x mass Bi alloys (x = 5, 10, and 58 mass %). The pasty (mushy) range, the type of solidification path

The g Factor of the Bound Electron in Hydrogenlike Carbon

January 1, 2001
Author(s)
H Haeffner, N Hermanspahn, H -. Kluge, G Marx, W Quint, S Stahl, T Valenzuela, G Verdu, G Werth
The experimental determination of the magnetic moment of the bound electron in hydrogen-like ions is an important test of the theory of quantum electrodynamics in strong Coulomb fields. It represents a clean test of pure QED effects because it is not very

The GAMS4 Flat Crystal Facility

January 1, 2001
Author(s)
Ernest G. Kessler, Maynard S. Dewey, R Deslattes, Albert Henins, H G. Borner, M Jentschel, H Lehmann
A high-resolution flat crystal gamma-ray facility, GAMS4, has been constructed at the high flux reactor at the Institut Laue-Langevin (ILL), Grenoble, France. The facility is located at the exit of a through-tube equipped to place sources in a neutron flux

The Influence of Grain Size on the Roughening Behavior of Al-Mg Alloys

January 1, 2001
Author(s)
Mark R. Stoudt, Richard E. Ricker
The discontinuouis plastic flow exhibited by numerous aluminum alloys presents significant challenges to the use of aluminum alloys in many automotive applications. The inhomogeneous morphology of the surface asperities generated during metal forming is

The Interdependent Networked Community Resilience Modeling Environment (IN-CORE): Science, Structure and Examples

January 1, 2001
Author(s)
John van de Lindt, Daniel Cox, Paolo Gardoni, Jong Lee, Jamie Padgett, Therese P. McAllister, Andre Barbosa, Harvey Cutler, Shannon van Zandt
ABSTRACT: Community resilience is the ability of a community to plan for, withstand, and recover from a natural hazard such as an earthquake or flood. Advancing community (or urban) resilience requires: (1) an understanding of how the physical

Author(s)
Billy W. Mangum, G T. Furukawa, Kenneth G. Kreider, Christopher W. Meyer, Dean C. Ripple, Gregory F. Strouse, Weston L. Tew, Robert D. Saunders, Bettye C. Johnson, Howard W. Yoon, Michael R. Moldover, Charles E. Gibson
The International Temperature Scale of 1990 (ITS90) is defined from 0.65 K upwards to the highest temperature measurable by spectral radiation thermometry, the radiation thermometry being based on the Planck radiation law. Part I of this paper describes

The Kilogram and Measurements of Mass and Force

January 1, 2001
Author(s)
Zeina J. Kubarych, Simone L. Yaniv
This paper describes the facilities, measurement capabilities, and ongoing research activities in the areas of Mass and Force at the National Institute of Standards and Technology (NIST). The first section of the paper is devoted to mass metrology and

The Laboratory Founded by Van der Waals

January 1, 2001
Author(s)
Johanna Levelt Sengers
During the past century, the Van der Waals Laboratory at the University of Amsterdam has been the principal provider of reliable fluid property data over large ranges of pressure and temperature. This paper describes the history of the laboratory, starting

The Magnetic Order of Cr in Fe/Cr/Fe(001) Trilayers

January 1, 2001
Author(s)
Daniel T. Pierce, John Unguris, Robert Celotta, Mark D. Stiles
The temperature dependence of the short period oscillatory coupling in Fe/Cr/Fe(001) whisker trilayers, when analyzed in light of recent theory, provides strong evidence that incommensurate spin density wave antiferromagnetic order is induced in the Cr
