Some of the specific materials

Advanced Materials Design: Structural Applications

Ongoing
Designing New High Temperature Co Superalloys In collaboration with the NIST CHiMaD center, an ICME approach in being used to develop new Co superalloys that are strengthened using an ordered FCC (L1 2) phase (similar to the related Ni-based superalloys). The design goals for these alloys include

Atomistic Potentials and the Future of Nanomaterials Metrology

Ongoing
Atomistic simulations are increasingly being used as a tool to understand and predict properties of materials in systems, such as nanomaterials, where direct measurement is time-consuming or extremely difficult. The success of atomistic simulations depends critically on the fidelity of a specific

Atomistic tools for structure-property investigations

Ongoing
Interatomic Potential Repository The Interatomic Potentials Repository (IPR) provides a source for interatomic potentials (force fields), related files, and evaluation tools to help researchers obtain interatomic models and judge their quality and applicability. The files provided are of known

Automotive Lightweighting

Ongoing
The US auto industry spends $600M per year fixing and tweaking forming dies that do not make correct parts. The primary reason that the dies are inaccurate is that the computer models of the dies utilize materials models that are inaccurate. Upon surveying our industrial partners, we determined that

Autonomous Scanning Droplet Cell

Ongoing
Corrosion impacts a broad spectrum of application areas including infrastructure, transportation, and the military. The annual price tag for corrosion mitigation and remediation is 3.4 % of the US GDP. The team is particularly interested in discovering new metallic glasses (metals without long range

Charpy Machine Verification Program

Ongoing
Impact testing is required for many critical applications in the construction, machinery and equipment, defense, and energy markets. Charpy testing provides data needed to ensure the quality and reliability of structural steel products. Over 1,000 machines per year are evaluated for conformance with

Chemical Metrology for Metals, Ores, and Related Materials

Ongoing
In the arena of industrial commodities, the primary challenges are to provide measurement tools and reference materials that allow U.S. industry to establish comparability of measurement results to results obtained by customers, competitors, and regulators for the basic chemical properties of

Data Driven Decision Support for Additive Manufacturing

Completed
Objective To develop and deploy the metrics, models, and best practices for using product definition, advanced analytics, and machine learning methods in additive manufacturing design and process planning to reduce lead times and support first-part-correct goals. Technical Idea Future advancements

Data Integration and Management for Additive Manufacturing

Completed
Objective Data plays the most critical role in linking AM lifecycle and value chain activities and streamlining the AM development process. While the AM data from a single build is essential for establishing part traceability, when methodically collected, the full processing history of thousands of

Designing the Nanoworld: Nanostructure, Nanodevices, and Nano-optics

Ongoing
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the

Developing a Materials Innovation Infrastructure

Ongoing
Phase Field Community Hub ( PFHub) and Benchmarks The Phase Field Community Hub provides a framework that supports phase field practitioners and code developers participating in an effort to improve quality assurance for phase field codes. The main thrust of this effort is the generation of a set of

DFT Repositories and Informatics

Ongoing
Historically, the printed article has served as the medium de rigueur for the dissemination of scientific information. This works well when the context and results of an experiment or theory fit on a few pages; however, it is insufficient as a publication medium for many computational studies. For

Dynamic Plasticity: Non-Equilibrium Mechanics

Ongoing
The optimization of high-speed machining processes through powerful finite element modeling techniques is an important pathway to American manufacturing competitiveness in an increasingly competitive global marketplace. Quantitatively accurate simulations of machining rely on robust constitutive
