Precursor Material Qualification

Completed

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, size

Qualification for AM Feedstocks, Machines and Processes

Completed

Objective - To develop, utilize, and analyze test methods and protocols for characterizing the feedstocks, machines, and processes in metal-based additive manufacturing to enable optimum usage and to reduce the cost and time needed for qualification. What is the Technical Idea? Qualification of AM

Cross section of a SAC solder joint in a BGA, with sketches of potential micro specimens

Small Scale Mechanical Testing

Ongoing

Knowledge of a material’s mechanical properties is key to designing safe and reliable structural components for applications ranging in size from medical implants to large civil engineering structures. Traditionally, a material’s mechanical properties are measured by performing mechanical tests on

Strain Tensor Tomography Reconstruction Algorithm

3D Strain Mapping: Transmission Bragg Edge Strain Tensor Tomography (TBESTT)

Ongoing

The techniques available for making predictions of structural component lifetimes are currently limited to 2D. For example, in linear elastic fracture mechanics, the crack tip stress state, used to relate crack growth rates to lifetime, has only been calculated for simple geometries (e.g. compact

Sustainable Metals Processing and Alloy Development

Ongoing

Foundational measurement science is being developed to support sustainable innovations through alloy design and optimization. The integration of experiments and computational thermodynamics and kinetics tools with mechanistic models enables the prediction of key processing-structure-property
