Abstract Scope |
In this talk we present the recent efforts of developing in-situ mechanical property measurement capabilities at Idaho National Laboratory (INL) using laser ultrasound techniques. In laser ultrasound measurements, a pump laser is used to introduce the acoustic wave or generate resonant vibration in the testing sample, which is captured by using a probe laser (usually a laser interferometry) through measuring the displacement of the sample surface. Young’s modulus, share modulus, and other constants in elasticity tensor, can be extracted from an inverse fitting procedure, from which the phase transition and/or recrystallization of alloy materials can be monitored in a desired temperature range. Using a similar mechanism, a fiber-based system was designed and tested in the INL Transient Reactor Test Facility. |
