The performance requirements of modern components in nearly every industry are ever increasing in parallel with constant efforts to reduce production cost and time. This has placed a greater importance on the understanding and control of process effects such as residual stress. X-ray diffraction (XRD) is a standardized and industry accepted method for determining residual stress in crystalline materials. This webinar provides a comprehensive explanation of the method with an emphasis on the value of residual stress depth profiles.
Magnetic Barkhausen Noise as an Alternative to Nital Etch for the Detection of Grind Temper on Gears

In September 2018, Flight Global reported on an incident that occurred on a commercial aircraft in which an axle fatigue crack led to a failure of the left nose landing gear axle and separation of the left nose wheel. “The cause of the abusive grinding could not be determined, but the abusive grinding would probably have been identified if a post-grinding Barkhausen inspection had been carried out.”
See the hidden damages with RoboScan. New video now available.
Check out GearScan 500 video. GearScan 500 allows for fast detection of common manufacturing problems such as grinding re-temper burn, heat treatment, and stress related defects.
