Did you know that Barkhausen noise turned 100 years this year? Barkhausen noise was discovered in 1919 by a German physicist named Heinrich Barkhausen. Industrial applications for the Barkhausen method began in 1980 and today it is a widely recognized non-destructive testing method for grinding burn detection, material characterization, and heat treatment defect testing. Follow the timeline and see what has happened over the last 100 years.
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.
