Abstract: The change of microscopic surface internal stress depend on the passage of time and high vacuum annealing in Twisting work materials were studied by the X-ray. The following results were obtained from the experiment. (1) Immediately load off, the round bar specimen which was subjected a twisting deformation have a compressive internal stress together with a Longitudinal direction or a Tangential direction in the surface of specimen. (2) The recovery of surface internal stress finished about 48 times, get to a stable condition together with a 0.2% carbon steel (S20C), or a high tensile aluminum alloy (17S) and a electrolytic copper (CuB-1). (3) In the neighbourhood of the recrystallization temperature of each materials, the surface internal stress and the value of half breadth were exibited the heaty decrease. The surface internal stress point out a remarkable decrease, according to the twisting deformation become larger. (4) In a 0.2% carbon steel (S20C), (211) diffraction line tend to separetes K_<α1> and K_<α2> at between 350℃ and 450℃. In a high tensile aluminum alloy (17S), (333) diffraction line separetes K_<α1> and K_<α1>, at 250℃, it seems that the recrystallization occuring at these temperature.
