In the present work, the ultrasonic velocity measurement was used as a non-destructive technique for flow stress determination of a twinning induced plasticity steel. For this purpose, first, a relationship between mechanical twinning and ultrasonic velocity was found out and then, it was used in the flow stress model previously suggested by the authors. Comparison of the obtained results with the experimental values revealed a good agreement.
