An automated system for a rapid and precise X-ray stress measurement using a personal computer is developed. The block diagram of the system and a flowchart for the stress measurement method are described. Of the various method, the method most suitable for the material measured can be programmed in this system. The residual stress in a hardened steel having a broad diffraction line (half-width of 7.2゜) could be measured in six min with a small standard deviation of 13 MPa by the Gaussian curve method using the sin^2ψ method. Both the oscillation method and the fixed ψ method using the Gaussian curve method allow the X-ray stress measurement of coarse-grained steels ; the sin^2ψ diagram obtained by these methods showed a good linearity. The residual stress measurement of an annealed chromium powder gave almost zero stress values, -3.2 to 2.9 MPa depending on the method used, showing a high accuracy of the system.
