Detection and simulation experimental analysis of tungsten inclusions in TC25 alloy parts
The TC25 titanium alloy disc parts forged by a certain factory underwent water immersion ultrasonic testing and X-ray testing,and one of the parts showed a defect on the outer wheel edge,which was not detected by water immersion ultra-sonic testing,but detected by X-ray testing.Research was conducted on this issue.Simulated defect detection experiments and energy spectrum analysis were carried out to determine the properties and characteristics of the defect.The experimental results showed that X-ray inspection was effective for tungsten inclusions.Energy spectrum analysis showed that the propor-tion of tungsten in the central area of the inclusion was close to 100%.In view of this defect,the subsequent TC25 alloy discs need to undergo forging,heat treatment(double annealing),rough machining and X-ray inspection before delivery.
