| Résumé | The recrystallization of hot-rolled aluminum strips was monitored inline after inline annealing at Commonwealth Aluminum Corporation (CAC) using-laser ultrasonics. The non-contact measurement is based on sensing the ratio of the compressional to the shear sound velocity in the strip thickness direction. This ratio is insensitive to strip thickness variations and varies with crytallographic texture and temperature. Therefore, recrystallization is sensed as a change of texture, from a rolling to an annealing texture. A pyrometer is used to decouple temperature and texture effects on the velocity ratio. The measurements were made on two alloys: AA5754 and AA5052. The capabilities and limitations of the sensor are discussed. |
