In the Canton laboratory of The Timken Roller Bearing Company, this General Electric XRD-3 diffraction unit charts directly the residual elastic stress in high-hardness steels.
X-ray now measures residual elastic stress in high-hardness steels Timken Company metallurgists achieve high accuracy with GE XRD-3 x-ray diffractometer Valid evidence that x-ray diffraction can provide important information concerning the stress condition in hard steel parts has been published by metallurgists at The Timken Roller Bearing Company, Canton, Ohio. This development presents an accurate, practical method of measuring the residual elastic stress in highhardness steel. With a General Electric x-ray diffraction unit, they obtained measurements accurate enough for engineering usage from a reasonably small test area (about Vi-
inch square). And the results checked with electric strain gauges. Non-destructive testing with GE x-ray diffraction units has found application in many fields. Among them: chemical, petroleum and ceramic, in addition to metallurgical. If you have a difficult diffraction problem in your plant, check to see if General Electric has met one like it. Or write for a reprint of a paper describing the above mentioned development. Address X-Ray Department, General Electric Company, Milwaukee 1, Wisconsin, Rm. UU-10. You can put your confidence in —
