1. The Pre-Wetting Transition at Anti-Phase Boundaries: An Atomistic Modeling Study of Ni(sub 3)Al
Published: 6/11/2008
Authors: Chandler A. Becker, Yuri Mishin, William J Boettinger
Abstract: Using an embedded-atom model for NiAl alloys, we have examined interfacial properties of the Ni/Ni(sub3)Al system, concentrating on properties of the anti-phase boundaries. These interfaces between gamma prime phases can undergo a pre-wetting transi ...

2. Recommended Practice Guide: DTA and Heat-Flux DSC Measurements of Alloy Melting and Freezing
Series: Special Publication (NIST SP)
Report Number: 960-15
Published: 11/1/2006
Authors: William J Boettinger, Ursula R Kattner, Kil Won Moon, John Perepezko
Abstract: This document is focused on differential thermal analysis (DTA) and heat-flux differential scanning calorimetry (HF-DSC) of metals and alloys. A thermal analysis guide focused only on metals and alloys is appropriate because they behave quite differ ...

3. Numerical Modeling of Diffusion-Induced Deformation
Published: 9/11/2006
Authors: J A Dantzig, William J Boettinger, James A Warren, Geoffrey B McFadden, Sam Ray Coriell, R F Sekerka
Abstract: We present a numerical approach to modeling the deformation induced the the Kirkendall effect in binary alloys. The governing equations for isothermal binary diffusion are formulated with respect to inert markers and also with respect to the volume ...

4. Whisker Formation in Pb-Free Surface Finishes
Published: 9/11/2006
Authors: Gery R Stafford, Maureen E Williams, C E Johnson, Kil Won Moon, Ugo Bertocci, William J Boettinger
Abstract: High purity bright Sn, Sn-Cu and Sn-Pb layers measuring 3,7 and 16 microns thick were electrodeposited onto phosphor bronze cantilever beams in a rotating disk apparatus. Beam deflection measurements within 15 min. of plating proved that all electro ...

7. Whisker & Hillock Formation on Sn, Sn-Cu and Sn-Pb Electrodeposits
Published: 11/11/2005
Authors: William J Boettinger, C E Johnson, Leonid A Bendersky, Kil Won Moon, Maureen E Williams, Gery R Stafford
Abstract: Bright Sn, Sn-Cu and Sn-Pb layers, 3, 7 and 16 mm thick were electrodeposited on phosphor bronze cantilever beams in a rotating disk apparatus. Over a period of several days, Sn-Cu deposits develop 50 mm contorted hillocks and 200 mm whiskers, pure ...

10. Examination of Multicomponent Diffusion Between Two Ni-Base Superalloys
Published: 9/11/2005
Authors: Carelyn E Campbell, William J Boettinger, T Hansen, P Merewether, B A Mueller
Abstract: The interdiffusion at 1293 degree C between two multicomponent Ni-base superalloys, Rene-N4 and ene-N5, was assessed by measuring the composition vs. distance curves and by comparing the measured curves to predictions obtained using a diffusion mobil ...
