is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. ABSTRACTThe objective was to study the mechanical properties of a magnesium alloy welded by a CO 2 laser. Residual stresses were measured by X-ray diffraction. They were calculated by the classic sin 2 Ψ method in the isotropic zones by using the orientation distribution function

“…By presenting a strong texture and an important loss of aluminum, the superficial layer is more sensitive to plastic deformation in the plane compared to the heart of the weld line which is isotropic (Hsiao et al, 2000). These results can be compared to a thin coat deposit because these thin coatings are textured and the maximum stresses are found at the interface (Pina et al, 1997;Cevat Sarioglu 2006).…”

“…High tensile residual stresses and large density of micro-cracks present in the electroplated deposits are responsible for reduction in its fatigue strength (Nascimento et al, 2001). Hard chrome electroplated coatings deposited by direct current (DC) reportedly possess strong crystallographic texture ({111} fiber texture) that increases in the core of the coating with the growth in the thickness (Pina, 1997). …”

Non-destructive characterization of surface microstructure of an engineering component is an important parameter to assess its fitness to function in the given service conditions. The paper describes various case studies performed in authors' laboratory involving use of portable X-ray diffraction based residual stress analysis system to examine and understand the micro-structural state of the investigated surface. A significant decrease in full width at half maximum (FWHM) of gamma(311) diffraction peak from about 4.2° in the cold worked state to about 2.5° in the annealed/surface melted state was recorded for austenitic stainless steel. In case of 0.4% carbon steel there is sharp increase in FWHM of alpha(211) diffraction peak from about 2° in the as received condition to about 5-6° in the laser hardened condition. Crystallographic texture developed during electro-plating of chromium on stainless steel, could be detected from the strong intensity of alpha (211) peak of chromium at about 19° to the surface normal with respect to all other X-ray inclination angles (ѱ) during residual stress measurement. The results show that FWHM and intensity variation of the diffraction peak are two sensitive parameters for characterization of surface microstructure. Change in FWHM has been used to detect machining-induced cold deformation and evolution of re-crystallized grains in austenitic stainless steel and formation of hard martensite in laser transformation hardened ferritic steel. Variation in the intensity of diffracted peak with respect to X-ray inclination angle provided valuable information regarding crystallographic texture in hard chrome plated deposits.
