ORNL’s Ralph Dinwiddie uses infrared cameras to create heat maps of working materials that reveal their thermal properties and subsurface structure. This 1998 image of an aging aircraft’s engine cowling revealed severe subsurface corrosion.
Scientists at the Department of Energy’s Oak Ridge National Laboratory are pioneering the use of infrared cameras to image additive manufacturing processes in hopes of better understanding how processing conditions affect the strength, residual stresses and microstructure of ...

Understanding where and how phase transitions occur is critical to developing new generations of the materials used in high-performance batteries, sensors, energy-harvesting devices, medical diagnostic equipment and other applications. But until now there was no good way to study a...
Using high-performance computing, ORNL researchers are modelling the atomic structure of new alloys to select the best candidates for physical experimentation.

The Department of Energy’s Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological

Quasiparticles—excitations that behave collectively like particles—are central to energy applications but can be difficult to detect. Recently, however, researchers have seen evidence of quasiparticles called negative trions forming and fading in a layer of semiconducting mate...

An ORNL-University of Rome study has delivered direct evidence of high-temperature superconductivity at the interface of two insulating oxide materials. Electron microscopy at ORNL showed that superconductivity arises from oxygen ions (circled in white) t
Electron microscopy at the Department of Energy’s Oak Ridge National Laboratory is pointing researchers closer to the development of ultra-thin materials that transfer electrons with no resistance at relatively high temperatures. The study delivers direct evidence of high-tem...
The “Big, Deep and Smart Data Analytics in Materials Imaging” workshop

In the Stone, Bronze and Iron Ages, the state of the art of materials science defined technology’s zenith and accelerated economies. Now, in the Information Age, data is beginning to drive the development of advanced materials, from photovoltaics for solar energy and superconductors for efficient el...

Developed by Oak Ridge National Laboratory researchers, CIRFT bends and vibrates used nuclear fuel rod segments to test the impact of normal traveling conditions—before the fuel rods ever leave the premises.
Moving rods of spent nuclear fuel (SNF) to interim storage or a geologic repository requires road or rail travel. Although a heavy shielding cask protects the rods, long distance transportation subjects SNF to vibrations, sudden movements and other potentially agitating for...

From the bluebird painting propped against her office wall and the deer she mentions seeing outside her office window, Linda Lewis might be mistaken for a wildlife biologist at first glance. But rather than trailing animal tracks, Lewis, a researcher at the Department of Energy’s Oak Ridge National Laboratory, is more interested in marks left behind by humans.

With more than 30 patents, James Klett is no stranger to success, but perhaps the Oak Ridge National Laboratory researcher’s most noteworthy achievement didn’t start out so hot – or so it seemed at the time.
