Phase Diagrams for Zirconium and Zirconia Systems

February 19, 2017
Author(s)
H Ondik, H F. McMurdie
This compilation is the first volume in the Phase Equilibria Diagram series focused on a single element, zirconium. The volume combines over 400 new results with diagrams and commentaries published previously to form a focused collection of 1020 diagrams

Phase Equilibria Data for Electronic Ceramics Published

February 19, 2017
Author(s)
Terrell A. Vanderah
The first volume of a collection of phase diagrams focused on the increasingly important field of electronic ceramics was presented to the American Ceramic Society (ACerS) at its annual meeting in April 2003. The new volume details the phase equilibria of

Phase Equilibria Diagrams - Volume XIII: Oxides

February 19, 2017
Author(s)
Robert S. Roth
This volume is the thirteenth of the topically-oriented series of phase diagram compilations and the eighth to appear since the National Institute of Standards and TEchnology (NIST) and the American Ceramic Society (ACerS) embarked on a jointly-sponsored

Phase Equilibria of the High Tc Superconductors in the (Bi, Pb) -SR-Ca-Cu-O System

February 19, 2017
Author(s)
Winnie Wong-Ng, Lawrence P. Cook, W Greenwood, Anthony J. Kearsley
Applications of (Bi,Pb)-Sr-Ca-Cu-O phase equilibria include material synthesis, melt processing and single crystal growth. Both liquidus and subsolidus data are of central importance. For the determination of liquidus data, we have used a wicking technique

Phase Relations in Ba-(Nd,Eu,Gd)-Cu-O Coated Conductor Films

February 19, 2017
Author(s)
Winnie Wong-Ng, Igor Levin, Joseph J. Ritter, Lawrence P. Cook, Guangyao Liu, Makoto Otani, Christopher E. Lucas, Shailee P. Diwanji, Ron Feenstra, P Goyal, Mark D. Vaudin
Knowledge of phase relations in thin films of Ba2RCu3O6+x (where R=lanthanides or mixed lanthanides) is needed to guide the processing of coated conductors. High-temperature X-ray diffraction studies of Ba2RCu3O6+x films deposited using the

Phase-Correct Bond Lengths in Crystalline-Ge x Si l-x Alloys

February 19, 2017
Author(s)
Joseph Woicik, K E. Miyano, C A. King, R W. Johnson, J G. Pellegrino, T L. Lee, Z H. Lu
Extended x-ray absorption fine structure performed at the Ge-K edge has determined the Ge-Ge and Ge-Si bond lengths in a series of crystalline-Ge l-x alloys (x [greater than/less than] 0.5) to be compositional dependent. This high-precision measurement was

Polarization Dependence of Raman Peak Heights in the Absence of an Analyzer

February 19, 2017
Author(s)
Grady S. White, L M. Braun, M I. Bell
The general expression relating Raman scattering intensity to incident and scattered polarization directions is modified to account for an experimental configuration without an analyzer. This expression, combined with the known polarizability tensors for

Practical Intrinsic-Error Bounds for X-Ray Computed Tomography

February 19, 2017
Author(s)
R D. Spal
Images produced by x-ray computed tomography contain intrinsic error due to the limited spatial resolution of the technique. Two bounds on the mean intrinsic error over a specified region are determined, given only minimal information about the object

Predicting Fracture Resistance of Brittle Crystals

February 19, 2017
Author(s)
Grady S. White, Stephen W. Freiman, Lin-Sien H. Lum
A simple expression is derived relating fracture surface energy to easily measured material properties, i.e., the elastic Young's modulus and the equilibrium atomic plane spacing via a proportionality constant, k. This expression appears to be independent

Predictive chemical kinetic model for lubricant performance: bench testings

February 19, 2017
Author(s)
Stephen M. Hsu, C I. Chen
Bench tests have been used to screen lubricants and additives for industrial fluids in machinery applications for a very long time. As technology becomes more sophisticated in terms of materials, controls, and design, the need for simple, quick, and cheap
