A versatile automated system for X-ray stress measurement using a microcomputer has been developed on the basis of conventional techniques and the fundamental study on X-ray stress measurement using the Gaussian curve method previously proposed by the author. The simultaneous control of the three stepper motors on the goniometer by use of three motor controllers allows both rapid measurement and the use of various measuring methods. The most appropriate method for each material is programmable in this system. Residual stress values of a hardened steel were measured by the iso-or side-inclination method using the fixed time or fixed count method agreed within the scatter of the measured values. The η oscillation method was found to be most useful for stress measurement of coarse grained steels. The system can also be used for evaluating diffraction line widths by using the Gaussian curve parameter.
