In the processing of TC4 titanium alloy profile, the "peeling" defect appeared at the punching position, which led to the product being scrapped. For the reason of positioning quality problem, the failure analysis was carried out on the punching area of titanium alloy profile. Through metallographic observation and microstructure analysis, it was found that the "peeling" phenomenon in the punching area was finally located in the internal delamination defect of titanium alloy profile, which was caused by the folding during the hot deformation of profile and the extension during the further extrusion deformation. When the hole is punched, the defect is deformed by the machining force, forming a macroscopic "peeling" phenomenon.
