Ultrasonic roll bite measurements in cold rolling – Roll stress and deformation [PDF]
Journal of Materials Processing Technology, 2017 In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity. To control the process, several online measurements are usually carried out such as the rolling load ...

Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage
Journal of Manufacturing and Materials Processing, 2023 The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...

Attenuation of ultrasonic waves in rolled metals
The Journal of the Acoustical Society of America, 2004 Scattering of ultrasonic waves in polycrystals with texture is studied in this article. The attenuations of the three wave modes are determined as a function of dimensionless frequency and propagation direction, respectively, for given orientation distribution coefficients (ODCs).

Ultrasonic Characterization of Rolling and Recrystallization Textures in Aluminum [PDF]
Texture, Stress, and Microstructure, 1996 Crystallographic texture, which plays an important role in many forming operations, is developed during sheet metal processing. Improved product quality could be achieved if the texture could be measured, quickly and inexpensively, during different stages of the processing.
