Light Materials Microstructural and Mechanical Characterization

National Laboratory: 
Lawrence Livermore National Laboratory
Oak Ridge National Laboratory
Characterization Class: 
Extreme Environment Testing
Processing/Manufacturing Class: 
Fabrication and synthesis
Description: 

Staff from Oak Ridge and Lawrence Livermore national laboratories compose an established materials characterization team with long-term experience in mechanical and microstructural measurements under various environments. Together, they are working toward developing high-strength/high-performance aluminum and magnesium alloys.

Capability Bounds: 

Capability limitations are subject to desired measurements.

Unique Aspects: 

ORNL and LLNL are an established team, who are developing advanced aluminum alloys and providing advanced, high-resolution, in situ computed tomography (CT); synchrotron measurements under strain/stress and at elevated temperatures; microscopies (transmission electron/scanning electron microscopy); neutron scattering; and high magnetic field and electromagnetic processing.
Capabilities include inert atmosphere-induction furnaces, capable of heating materials to more than 2000°C with a 200-kW, dual-frequency commercial-scale induction power supply. In situ elevated temperature physical property measurement and analysis capabilities can track phase transformation kinetics, enabling rapid development of heat-treatment schedules. Industry-compatible casting methods also have been established and successfully proven in domestic foundries, as well as high-resolution chemical/electronic structure mapping of grain boundaries and interface structures.
