Material Flammability Characterization

Ongoing
This project develops a database that includes tools, measurement data, material properties, and validation data to enable quantitative prediction of material flammability behavior, such as ignition, steady burning, and fire growth.

Material Qualification

Ongoing
Objective To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological...

Materials Data Curation System

Ongoing
The NIST Materials Data Curation System (MDCS) provides a means for capturing, sharing, and transforming materials data into a structured format that is XML based amenable to transformation to other formats. The data are organized using user-selected templates encoded in XML Schema. These templates...

Materials Data Repository

Ongoing
In support of NIST's MGI goals, the NIST materials data repository provides a concrete mechanism for the interchange and re-use of research data on materials systems. The NIST repository is principally a file repository, accepting data in any format. To mitigate the opacity of binary data, and to...

Materials Design Toolkit

Ongoing
Microstructure evolution can be simulated using the CALPHAD approach and phase based models using thermodynamics software and models. The simulated microstructure is then evaluated by constitutive models and PyMKS. The optimization algorithms use the performance of the alloy to direct the search...

Materials Informatics

Ongoing
To develop the need data infrastructure and informatics tools, NIST is focusing on three areas: data curation, data infrastructure, and data access. Data curation efforts include efforts to develop a phase-based materials ontology to ensure that the data is represented in a semantically...

Materials and Structures for Resilience Program

Ongoing
Objective To improve building codes, standards, and engineering practice by developing and deploying advances in measurement science that enhance the robustness, resilience, and durability of materials and structures against natural and manmade hazards. Technical Idea The Materials and Structures...

Materials Testing in Extreme Environments

Ongoing
Hydrogen is known to have a deleterious effect on steels and other metals, but steels are the most cost-effective and commonly used materials for pipelines and pressure vessels. We are collaborating with the code bodies (ASME B31.12 and ISO 11114-4), DOT, and DOE, to enable the implementation of...

Mathematics of Metrology: Foundations and Applications

Ongoing
Mathematics plays an important role in the science of metrology. Mathematical models are needed to understand how to design effective measurement systems, and to analyze the results they produce. Mathematical techniques are used to develop and analyze idealized models of physical phenomena to be...

Measurement Assurance for Quantitative Cell Imaging by Optical Microscopy

Ongoing
Light microscopy is unparalleled as a quantitative technique for studying cell biology, but assuring that the results of measurements and analyses are accurate, repeatable and sharable is challenging. Here we provide information on reference materials, protocols and approaches for evaluating the...

Measurement, Metrics, and Assurance

Ongoing
The Structured Software Assurance (SSA) task is investigating a methodology known as "structured assurance case models," which have been used extensively in assuring safety-critical systems and applications, for their potential application in assuring other software system qualities, such as...

Measurement and Prediction of Local Structure

Ongoing
Functional materials enable applications in the computer, data storage, wireless communication, and energy sectors. The properties of many of these systems are critically dependent on deviations of local atomic arrangements from the global average of the crystal. No single measurement technique can...

Measurement Quality in Hydrogen Storage R&D

Ongoing
The hydrogen storage project targets metrologies that assess kinetics and energetics of hydrogen charging and discharging in combinatorial structures as well as the degradation mechanisms that limit life of use. New capabilities are being developed and several existing measurement capabilities are...
