Abstract
The x-ray diffraction characteristics of different materials are discussed in this paper. It is found that the accurate determination of real stress is not easy to obtain when two diffraction peaks with low diffraction intensity are shown and the residual stress of stainless steel, aluminum, titanium alloy materials etc are determined by X-ray method. Five kinds of uniform intensity girders made from common carbon steel (Q235), austenite stainless steel (1Cr18Ni9Ti), martensitic stainless steel(A335P92), aluminium alloy(LY12) and titanium alloy(TA15) are determined repeatedly using uniform intensity girder demarcation method. It is proved by experiment results that X-ray diffraction peaks at some angles can’t well reflect the real change of stress.
