Backscatter Ultrasonic Analysis
Backscatter ultrasonic analysis is a method that uses high-frequency ultrasonic waves to detect material defects and embrittlement. It quantifies backscattering at microstructural inhomogeneities and grain boundaries.
Physical-Chemical Mechanism of Action
The method uses high-frequency ultrasonic waves that are reflected by the material. The backscatter of these waves is analyzed based on intensity and phase shift behavior.
Metallurgical Relevance & Welding Risks
Backscatter ultrasonic analysis detects material degradation, embrittlement, and other structural defects. Misinterpretation can lead to inaccurate results, affecting quality assurance.
Workshop Practice & Procedures
Use high-frequency ultrasonic equipment with specialized software for analysis. Ensure the material is clean and free of surface defects. The measurement should be performed in a calibrated environment.
