AI Technical Summary

Technical Problem

Current methods for characterizing microtexture regions in materials like titanium alloys are often destructive and fail to accurately assess microtexture levels, which can lead to premature failure in components due to dwell fatigue susceptibility.

Method used

A non-destructive ultrasonic characterization system that uses a controller and transducer to measure backscattered noise from microstructure variations, with controlled incidence angles and statistical analysis of peak amplitudes and frequency spectra to quantify microtexture levels, allowing for the identification of regions with higher service life potential.

Benefits of technology

Enables non-destructive evaluation of microtexture levels, improving the assessment of component service life and identifying regions that require specific heat treatments or scrapping, thereby enhancing the reliability of critical aerospace components.
