Application Summary AI generated

This standard specifies a nonlinear ultrasonic testing method for detecting and evaluating microstructure damage in materials, such as fatigue, creep, or thermal degradation. It is applied in industrial non-destructive testing contexts, particularly for assessing early-stage damage in metallic components used in aerospace, power generation, and heavy machinery. The method enables detection of microstructural changes that linear ultrasonic techniques cannot identify, supporting preventive maintenance and structural integrity assessments.
