2D Material Electronic Test

Electronic Material Characterization

Ongoing
Manufacturing optimized devices that incorporate newly-emerging materials requires predictable performance throughout device lifetimes. Unexpected degradation in device performance, sometimes leading to failure, is often traceable to poor material reliability. Reliability is rooted in the stability

AM Machine and Process Control Methods for Additive Manufacturing

Completed
Objective Develop algorithms, methods and standard protocols for Additive Manufacturing (AM) process control, and implement it with software and hardware tools for open control of AM systems to enable more flexible process optimization by manufacturers. What is the Technical Idea? Additively

Metrology for Multi-Physics AM Model Validation

Completed
Objective To provide reference data for the validation of multi-physics models of metal additive manufacturing processes to enable improvement of AM process models and more rapid and predictable process development for AM production by manufacturers. What is the Technical Idea? The Metrology for

Metrology for Real-Time Monitoring of Additive Manufacturing

Completed
Objective To develop and disseminate metrology methods, tools, data, and standards applied to in-situ monitoring of AM processes, such that manufacturers and their customers can accurately and precisely determine the quality of the fabrication process and resulting parts. What is the Technical Idea

Multiscale structure and dynamics in advanced technological materials

Ongoing
New technologies increasingly harness materials phenomena that operate across many length-scales: e.g., in selective gas adsorption, additive manufacturing, new alloy designs, or advanced concretes. To overcome technology barriers, it is no longer sufficient just to characterize the materials

NCAL: Diffraction Stress Measurement Under Applied Load

Ongoing
Using X-ray diffraction (XRD) techniques one can measure the full stress tensor just inside the surface of a sheet metal specimen under applied loading. This permits the measurement of biaxial stress states resulting from directly applied deformation (see NCAL: Multiaxial Material Performance) or

NCAL: Intermediate Strain Rate Testing

Ongoing
This project seeks to improve servohydraulic testing methods at intermediate strain rates by addressing the well-known problems associated with excessive stress oscillations (ringing) that currently limit our understanding of the mechanical behavior of engineering materials for loading conditions

NCAL: International Documentary Standards Activities

Ongoing
NIST Center for Automotive Lightweighting (NCAL) staff participate in many different international standards committees (e.g. ISO TC 164, ASTM E28 and D30); however, our main focus has been in the mechanical testing of metals and, to a lesser extent, composites. We work on the calibration and

NCAL: Materials Testing 2.0

Ongoing
The traditional approach to calibrating material models, known as Materials Testing 1.0, is a time-consuming and costly process that requires multiple experiments to be performed on different types of testing equipment. This not only results in high capital costs for testing machines but also leads

NCAL: Multiaxial Material Performance

Ongoing
Modern metal forming methods are designed and optimized using digital models of specific manufacturing operations. These models rely on a precise understanding of the mechanical behavior of sheet materials as they undergo multiaxial loading out to large plastic strains without failure (necking or

NCAL: NIST Center for Automotive Lightweighting

Ongoing
The ongoing development of new, advanced lightweight materials presents opportunities for the USA automotive industry to produce better, more reliable and less expensive products provided the new materials can be efficiently manufactured. The use of lightweight materials in automobiles, such as
Tension compresion fixturing with upper and lower loadcells and grips and lateral anti-buckling guides with pneumatic actuators

NCAL: Tension-Compression Testing

Ongoing
The inability to predict the mechanical behavior of new automotive alloys during forming has generated strong demand in industry for more advanced material models and test methods necessary to calibrate them. Industry is particularly interested in modeling the behavior of advanced sheet metals

Photonic Dosimetry

Ongoing
With this effort, NIST is responding to industry needs for traceable, measurement solutions that can resolve spatial variations of absorbed dose at the level of individual components on a silicon wafer or bacteria on surgical instruments. Presently, there is only limited traceability to national

Smart Manufacturing Systems Design and Analysis Program

Ongoing
Smart Manufacturing has the potential to fundamentally change how products are designed, manufactured, supplied, used, remanufactured and eventually retired. Current smart manufacturing implementations are mostly at the plant level, and use information technology, sensor networks, computerized

Technological Advances in Aquaculture

Ongoing
According to the NOAA Fisheries of the U.S. report, in 2020 U.S. seafood consumption was estimated at ~6B pounds (~2.7 x 109 kg). Of that, 85% is imported and U.S. exports have seen a significant decline. Globally, the U.S. ranked only 18th in aquaculture production (2020). NIST aims to enhance the
