Raman Stress Evaluation: Hydrostatic vs. Biaxial Calibration

February 19, 2017
Author(s)
L M. Braun, Grady S. White
Comparisons of two technical approaches for stress measurement based on the peak shifts associated with micro-Raman spectra are described. Stress values were obtained from evaluation of the relationship between peak shift and stress determined by both a

Rapid Detection of Thin-Film Interfacial Reactions by MEMS-DSC

February 19, 2017
Author(s)
Lawrence P. Cook, Richard E. Cavicchi, Yanbao Zhang, Mark D. Vaudin, Christopher B. Montgomery, William F. Egelhoff Jr., Martin L. Green, Leslie Allen
A MEMS-based differential scanning calorimeter (DSC) has been used to characterize the Ni/Si interfacial reaction in thin films at ramp rates of 940 C/s and 3760 C/s. The DSC devices were fabricated using CMOS semiconductor processing technology, and were

Relationship Between Microstructure and Wear of Dental Ceramics and Composite Resins

February 19, 2017
Author(s)
V S. Nagarajan, S Jahanmir, B Hockey, Victoria Thompson
The effect of microstructure on the wear mechanisms of glass-ceramics and resin composites was studied. Wear tests on both types of materials were conducted using a pin-on-disk apparatus. Wear of glass-ceramics increased with increasing mica platelet

Simulations of Microstructural Evolution: Anisotropic Growth and Coarsening

February 19, 2017
Author(s)
A R. Roosen, W Carter
Two-dimensional calculations of anisotropic growth and coarsening are illustrated. This model is intended to simulate the development of microstructure in materials like Silicon Nitride. The model is comprised of an ensemble of polygonal particles with

Spontaneous Ejecta From [Beta]-Eucryptite Composites

February 19, 2017
Author(s)
Ivar E. Reimanis, C Seick, K Fitzpatrick, Lin-Sien H. Lum, S Landin
Polycrystalline ceramic composites, comprised of primarily b-eucryptite (LiAlSiO4) and lithium aluminate (LiAl5O8) crystals, with a near-zero coefficient of thermal expansion were examined with indentation experiments. A unique behavior is reported

Standards for Biomaterials

February 19, 2017
Author(s)
Stephen W. Freiman, John A. Tesk
This paper is a summary of a workshop session during the Workshop on Biomedical Materials and Devices, held June 13-14, 2001. The workshop is part of a series of workshops and topical meetings organized by NIST in the area of biomedical technology. The

Structural Ceramics Database Update (April 2003)

February 19, 2017
Author(s)
R G. Munro, C P. Sturrock
An update of the NIST Standard Reference Database Number 30, the Structural Ceramics Database, has been completed. This update, designated SCD Update (April 2003), increases the number of source entries by 100 citations and increases the total number of

Subsolidus Phase Equiibria of the 2223 (Bi:Sr:Ca:Cu) Phase at 840 C to 850 C in Air

February 19, 2017
Author(s)
Winnie Wong-Ng, Lawrence P. Cook, F Jiang, L Swartzendruber, P Sastry
The subsolidus phase equilibria involving the Bi-2223(Bi 2Sr 1.9Ca 2.1Cu 3O 10+x) phase in the Bi-Sr-Ca-Cu-O system (BSCCO) were investigated at 840-850The subsolidus phase equilibria involving the Bi-2223(Bi2Sr1.9Ca2.1Cu3O10+x) phase in the Bi-Sr-Ca-Cu-O

Subsolidus Phase Relationships of the BaO-R 2 O 3 -CuO z (R=Tm and Yb) Systems Under Carbonate-Free Conditions at p o2 = 100 Pa, and T = 750 Degree Celcius and 810 Degree Celcius

February 19, 2017
Author(s)
Winnie Wong-Ng, Zhi Yang, Lawrence P. Cook
For applications of phase equilibria to coated conductor processing, phase diagrams constructed under carbonate-free conditions should be employed. Using special apparatus and a procedure for preparing carbonate-free precursors based on BaO, phase diagrams
