ActiveNon-destructive testing—Nonlinear ultrasonic testing method of microstructure damage
无损检测 组织结构损伤非线性超声检测方法
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.
