A programmable automated X-ray diffractometer has been developed, making use of a micro-computer and a commercial X-ray goniometer, in order to use it for materials evaluation by various new X-ray diffraction techniques. A scalar-timer and stepper moter controllers were newly designed using several highly efficient large-scale integrated devices {LSI} . The use of these devices could simplify greatly the electric circuits of the units, and could improve their reliability and maintenance. The viability of this system was confirmed by using an annealed mild steel and an aluminum oxide specimen. Accurate diffraction line profiles could be obtained by using the fixed time method. The diffraction line broadening of the mild steel caused by stretching and residual stress of the aluminum oxide were measured by the Gaussian curve method. They could be determined by using K_<α1> line profiles for materials whose K_<α1>, and K_<α2> lines are separated
