In FY 2009, the division used $2 million in ARRA funds, plus another $0.5 million in laboratory funds, to augment the mechanical test facility, providing unique capabilities to the division in high-strain-rate metrology and measurements targeting the automotive and other industries reliant on metal forming. Other strong facilities in the division include nanomaterials fabrication (semiconductor nanowires, magnetic and other thin films, and electrodeposition)

homojunction and CdTe-based heterojunction devices together with the modeling of these devices. Hydrogen Storage Project The objective of the 6-year, $6.1 million Hydrogen Storage project is to develop the metrologies necessary for the rapid, high-throughput measurement of the hydrogen content of novel materials proposed for hydrogen storage and for electrodes in nickelmetal hydride (Ni-MH)

Magnetic Nanoparticle Metrology The 4-year, $2.2 million Magnetic Nanoparticle Metrology project is showing that nanoparticles need to be interacting with each other in order to heat effectively for hyperthermia treatments, and recent work has shown that magnetic torque measurements can provide the information that small angle neutron scattering (SANS) measurements do in distinguishing between different suspensions of magnetic nanoparticles.

At the end of FY 2009, this group was made up of 10 permanent technical staff, 1 NRC postdoctoral researcher, and 1 term employee/student; and 6.2 associates (see footnote 1) provided significant contributions to the research program.

Mechanical Performance Under Extreme Conditions Project The objectives of this 9-year, $6 million project are to provide property data, metrology, and standard test methods for materials systems under extreme conditions for areas critical to manufacturing, homeland security, and energy infrastructure within the United States. The goals of the presented project are to develop new high-strain-rate measurement techniques and to provide more accurate and robust data for modeling material behavior under extreme conditions (e.g., manufacturing, transportation safety, law enforcement, fire, etc.)

An intermediate-strain-rate servo-hydraulic test frame has been purchased using ARRA funds to allow for testing at intermediate strain rates. This acquisition will allow NIST scientists and engineers to collect high-quality data over all strain rates from quasi-static to very high Kolsky bar rates.

Since that time, the experimental techniques have been refined, and the experimental results have been complemented with crystal plasticity modeling using crystallographic textures, in association with researchers in the Department of Materials Science and Engineering at Carnegie Mellon University. An additional exciting observation was the first prediction of transformation potentials in TRIP steels, which showed that initial crystallographic textures play a significant role in the TRIP effect.

The design of the Web site should be forward-looking, with the perspective of ultimately being able to be used by others to download externally produced data and to provide it to the wider materials community for assessment and use. This recommendation is consistent with the recent National Materials Advisory Board report on Integrated Computational Materials Engineering.6 6 National Research Council, Integrated Computational Materials Engineering: A Transformational Discipline for Improved Competitiveness and National Security.

NIST Atomistic Potentials Repository The expected duration for this project is FY 2008–FY 2013, with a budget of approximately $300,000 per year. This 5-year, $1.5 million NIST Atomistic Potentials Repository project is developing a public repository for interatomic potentials for use in atomistic simulations.

In particular, it has opportunities to work with other groups in the Metallurgy Division (Mechanical Performance and Magnetics) to develop similar data and model dissemination techniques for mechanical and magnetic properties.

There is a strong emphasis on the inherent linkage between thermodynamics and kinetics and the use of these tools in the development of models that enable the prediction of microstructure -- a key enabler for the prediction of complex properties, failure modes, and the discovery of new metrics for materials properties and performance. Recommendation: The Thermodynamics and Kinetics Group should work closely with other groups within the Metallurgy Division, especially the Mechanical Performance Group, to develop ICME tools.

Finding: Metrics of productivity are not always evident or uniformly articulated. Recommendation: Management should evaluate the utility of uniform metrics for such things as publications (e.g., h factor analysis)
