Episode 19 - Real-Time In-Situ Sensing of Microstructure Evolution using Laser Ultrasonics + Gleeble

Gleeble Webinar Series - Episode 19 Dr. Thomas Garcin and Dr. Brian Allen will present an overview of the laser ultrasonic system that can be coupled with a Gleeble. Laser-ultrasonics is a technology that enables non-contact ultrasonic measurements, using lasers to generate and detect ultrasound pulses. Unlike other ultrasonic technologies, it can be used on hot materials up to any temperature because there is no physical contact. Therefore, it is ideally suited for in-situ studies of solid metallic or ceramic materials up to their melting point. Days and weeks of metallurgical studies yielding a few measurements on quenched samples can often be replaced by a single in-situ laser-ultrasonic test, yielding hundreds of measurements in real time. Including in-situ measurement of recrystallization, grain growth, grain size, phase transitions and elastic constants.
