Effect of Wear Track Diameter on Tribological Behavior

February 19, 2017
Author(s)
S Jahanmir
Wear tests were conducted using a pin-on-disk tribometer to evaluate the effect of disk track diameter on the tribological behavior. High purity alumina balls were used as pins sliding against glass-ceramic (IPS empress 2) disks under distilled water

Effects of Large Grains on Transgranular Fracture Toughness

February 19, 2017
Author(s)
Stephen W. Freiman
This paper addresses issues of fracture for materials in which large grains, exist in a matrix of much smaller grains. Materials used for optical components, such as ZnS and ZnSe frequently fall into this category. For materials of this sort failure can

Effects of Polarity on Grain Boundary Migration in ZnO

February 19, 2017
Author(s)
Jong S. Lee, Sheldon M. Wiederhorn
Boundary migration of ZnO has been investigated using single crystals with defined crystallographic orientations. The migration rate of the basal C planes depended on the crystallographic polarity: Zn-terminated positive (0001)-planes. The migration in the

Energy Escalation Rate Calculator (EERC1.0-03)

February 19, 2017
Author(s)
L I. Schultz, S Fuller
The Energy Escalation Rate Calculator (EERC) computes an average annual escalation rate for fuel prices, based on the annual energy price forecasts of the Energy Information Administration (EIA) of the U.S. Department of Energy (DOE). This rate is used to

Enviromental Concerns Facing the Ceramics Industry

February 19, 2017
Author(s)
Stephen W. Freiman
Over the past few years, there has been increased attention paid by ceramic manufacturers in the United States to environmental issues facing their businesses. In a recent survey of its members, the environment was identified as the primary issue facing

Establishing a World-Wide Unified Rockwell Hardness Scale Using Standard Diamond Indenters

February 19, 2017
Author(s)
S Desogus, A Germak, H Ishida, T Polzin, H Yang, Jun-Feng Song, Samuel Low, David J. Pitchure
Recently developed microform measurement techniques have reduced the measurement uncertainties in the geometry of Rockwell diamond indenters. It is now possible to establish standard grade Rockwell diamond indenters characterized by high geometry

Experts Evaluate Pulsed Laser Deposition Technology

February 19, 2017
Author(s)
John W. Hastie, D W. Bonnell, D Chrissey
The National Institute of Standards and Technology (NIST, Gaithersburg, MD) and The Naval Research Laboratory (NRL, Washington, DC) jointly hosted a workshop entitled Pulsed Laser Deposition (PLD) Technological Barriers: Research Needs and Opportunities

Extracting Two Parameters From a P2 Orientation Distribution

February 19, 2017
Author(s)
Curtis Meuse, Joseph B. Hubbard
Individual molecules are seldom identical. This poses a problem for optical spectroscopy. For instance, if molecular property distributions are not characterized, differences in the distribution of molecular properties between sample and standards are

Factors Affecting the Service Life of Seams of EPDM Roof Membranes

February 19, 2017
Author(s)
Walter J. Rossiter Jr, Jonathan W. Martin
A quarter century ago, a revolution occurred in the U.S. low-sloped roofing industry with the introduction of a number of new membrane products including elastomeric and thermoplastic polymeric membranes and polymer-modified bituminous membranes. Today
