AbstractThis article presents laser-ultrasonic attenuation measurements in hot-rolled A36 and interstitial free (IF) steels at temperatures between 500°C and 1100°C. The development of laser-ultrasonics in recent years has allowed new attenuation measurements with significantly improved accuracy at these temperatures. The sudden variations of ultrasonic attenuation observed in this temperature range are related to microstructural changes caused by the austenite-ferrite phase transformation. These attenuation variations are also compared to dilatometry measurements.
