| Popis: | 39th Annual Review of Progress in Quantative Nondestructive Evaluation (QNDE), Denver, CO, JUL 15-20, 2012REVIEW OF PROGRESS IN QUANTITATIVE NONDESTRUCTIVE EVALUATION, VOLS 32A AND 32B; International audience; The interaction between ultrasonic waves and the polycrystalline microstructure of metals leads to structural noise and attenuation, which can cause significant losses in detection performances. Taking these phenomena into account in UT simulation can help designing suitable inspection procedures. It is possible to model them based on the intrinsic scattering coefficients of a material. Expressions of this coefficient valid for duplex elongated materials and for any mode and scattering direction are given in this communication. Structural noise from a titanium alloy was computed based on these expressions and is compared to measurement. |
