...Abstract Abstract An AISI type 303(Se) stainless steel eye terminal that was roll swaged on the end of a 9.5 mm diam wire rope cracked extensively after one year of service. A hairline crack that had initiated at the inner surface of the fitting was revealed by metallographic examination...

... surface of the tube were identified as fluorides from the brazing flux by chemical analysis. The nature of the crack, potential for corrosion due to residual fluorides and residual swaging stress in the tube prior to brazing, confirmed that failure of the tube end was due to stress-corrosion cracking...

...Abstract Abstract A 17-4 PH steering actuator rod end body broke during normal take-off. Results of failure analysis revealed that the wall thickness of the race was much below the design limits, thus causing the race to rest on the body's swaged edges rather than on the load carrying...

They thought that the fabrication procedure (shear spinning and swaging) performed at Marquardt may have caused the softening, which in turn may have contributed to the two TOW failures.

... as fluorides from the brazing flux. Because it was known that the tube end had been swaged before brazing without an intervening stress-relief treatment, because the residual fluorides represented a potential for corrosion, and because of the nature of the crack, it was deduced that the failure had resulted...

It is similar to neither upsetting nor swaging. Essentially a point deformation metal forming process, flow forming results in a part...

..., then a more suitable wire-rope construction may be necessary. Compacted/swaged (flattened) outer-wire surfaces, larger outer wires, and lang-lay wire ropes are more wear resistant than regular-lay ropes.
