Stress measurements with x-ray diffractometry on aluminum alloys. determination of the most optimized parameters of the measurement

Abstract

X-ray diffractometry is one of the basic methods of stress measuring. This method was used to measure stress distributions around rivets as described further in this paper. There were two types of riveted samples, nine types of samples made of rivet wire (after different types of treatment), the aluminium sheet sample with three measurement areas: plate with both cladding and anodized layer, plate after removing the anodized layer and plate after removing both cladding and anodized layer and the alminum alloy plate sample with chemically milled area which was anodized after that. Riveted samples were prepared to measure the stress distribution around the rivets and the samples of wire and the plate with three areas were prepared to check the effect of different types of treatment on stress state. The sample with the chemically milled cladding was prepared to choose the optimized measuremet parameters for stress measurements on alminum. © Springer Science+Business Media B.V. 2009.
