Laboratory, Carnegie Mellon University, and PulseRay. For the first time, the team has integrated three high-energy synchrotron x-ray techniques during mechanical testing to quantify the average elastic strain and stress tensor for each grain using far-field high energy diffraction microscopy (HEDM); map the grain shape and local crystallographic orientation within and between grains using near-field HEDM; and track the formation and spread of voids and cracks using micro-contrast tomography. Global testing group Exova unveiled its state-of-the-art $4.9 million These unique datasets provide insight into deformation Corrosion Centre in Dudley, UK.

Ceram, Staffordshire, UK, released a recording of its recent webinar, "Testing: With the development and validation of these new miMore Than Just Numbers." The lecture was presented by Dr. Richard White, crostructure modeling tools that can predict material behavior, who discussed case studies to show how testing has been used by industry to gain a competitive advantage. White also talked about how continual including variability and uncertainty, engineering design can be monitoring and detailed testing can help identify problems with materials, revolutionized by unlocking the true potential of the material's products, and processes; how measuring key performance characteristics capabilities, safety, and fuel efficiency. The economies of scale can avert potential problems; and how surface analysis of the outermost for materials affected by these advancements have the potential layers provides critical information. to save billions, according to researchers.
