Welcome

The Materials Performance Group

  • develops new and improved models, test methods and standards to accurately measure mechanical properties of advanced materials, such as high strength steel and aluminum alloys, as well as of conventional materials under both expected and extreme environmental conditions;
  • generates and disseminates reliable mechanical property data;
  • standardizes, both nationally and internationally, mechanical property test methods.

Programs/Projects
Fundamentals of Deformation — This project provides new measurement methods, property data and simulations for areas critical to US manufacturing, describing the mechanisms responsible for mechanical behavior. The mechanical …
 
Hardness Standardization — Our objective is to standardize and improve hardness measurement both in the U.S. and internationally. NIST is the U.S. National Metrology Institute (NMI) for hardness, and as such, is responsible …
 
Materials Codes and Standards for Hydrogen Distribution — The goal of this project is to enable the development of a scientific and technical infrastructure for the safe and efficient use of hydrogen as a fuel source. For example, figure 1 shows the …
 
Mechanical Performance - Extreme Conditions — This project provides property data, metrology, and standard test methods for materials systems under extreme conditions for areas critical to US manufacturing, homeland security, and energy …
 
NIST Center for Metal Forming — Our objective is to develop the measurement methodology, standards and analysis necessary for the US auto industry and base metal suppliers to transition from a strain-based to a stress-based …
