Defect Detection Analysis of 5083 Aluminium Alloy Thick Plate
Based on the analysis of chemical composition,macrostructure,fracture structure and microstructure of 5083 aluminium al-loy plate with dense spot defects found by ultrasonic inspection,the defect properties were determined,which provided a basis for the qualitative waveform of defects found by ultrasonic inspection,and provided a reference for process improvement.
