| Abstract Scope |
Optimizing metal performance relies on managing grain growth, crucial for enhancing reliability and functionality. Our recent research introduces an in-situ grain size determination system that integrates a quenching dilatometer (DIL L78/RITA) with laser ultrasound sonic (LUS) technology. The quenching dilatometer furnishes thermal history and phase transformation data, while LUS offers precise grain size and structure details. Combining these data sets obtained on the same sample during the heat or cooling treatment allows for a more comprehensive understanding of how thermal cycles affect microstructure. This synergistic approach enhances understanding of thermal cycle impacts on microstructure, aiding material optimization. Laser ultrasound measurements, combined with frequency-dependent ultrasonic attenuation modeling, yield real-time, in-situ grain growth insights during thermal treatments. Several application cases are discussed. |
