AMS 4919 Forming Cracks
AMS 4919 Forming Cracks
(OP)
I'm currently working on my first real failure investigation on some AMS 4919 (Ti 6242) formed parts. The parts in question have a material thickness of .034", and are formed in annealled condition. Parts at the time of forming are without alpha case contamination, However, we are seeing a high rate of failure during forming on the bend radius. I feel that these fractures are occuring due to surface defects (pits, scratches) in the bend radius. I am going to further investigate this problem, however I would like your opinions to whether this would be a valid hypothesis. Also, beyond verifing that there is no alphacase/surface contamination and observing the fracture surface, what other methods of analysis would you recommend.
