Materials Engineering Seminar

Date: Wed. 15 Feb, 2017 3:00 pm - 4:00 pm
Duration: 1 Hour
Location: Cramer Hall

Melissa Teague, Sandia National Laboratories, will present the Materials Engineering seminar series. Her talk is titled "Characterization and Modeling of Microstructural level Stresses in Brittle Materials." Recent advances in photoluminescence (PL) spectroscopy have established the potential to map residual stress variation with microscale spatial resolution (2 microns).Teague will present results from the mapping stress generated in bonded, mis-oriented bi-crystals and polycrystalline alumina to investigate the limits of PL spectroscopy as a microscale stress mapping tool. These results will be compared to microstructure models generated from electron backscatter diffraction (EBSD). 3 p.m. Wednesday, Feb. 15, in Camer 124
