Special Issue Information

Dear Colleagues,

The use of precipitation hardened aluminium alloys as structural materials in passenger carrying aircraft appears to be at a crossroads. Long range civil aircraft including the Boeing 787 and the Airbus A350 have fuselage and wing made from carbon fibre composites. However, it is not yet clear if the next generation of current short to medium range aircraft (Boeing 737 and A320) will follow this trend. Aluminium alloys can still compete from a material availability, structural efficiency and cost of ownership position. These established materials still offer a compelling choice for aircraft manufacturers. One of the requirements of the aluminium alloys used in aircraft is the heat treatment step. Quenching from the solution treatment temperature induces distortion in thin products (sheet, extrusions) and large magnitude residual stresses in thick products (forgings, plate). It is partly due to the complex management and consequences of these residual stresses that has led to the replacement of aluminium alloys with composite materials in aircraft structures.

To continue to compete with composite materials, the prediction, characterisation, management, control and consequences of residual stresses in precipitation hardened aluminium alloys still warrants further investigation. Studies themed around the optimisation of mechanical stress relieving techniques by the use of improved multiscale models of microstructural evolution during quenching are especially relevant. These models will be capable of predicting the microstructure as a function of quench path to account for the differences in cooling in the bulk material from surface to core in large scale components. This evolution of microstructure can then be used to quantify mechanical behaviour of the material, again as a function of location within the bulk, more specifically the yield and work hardening response of the material during plastic deformation applied during stretching or cold compression.

Papers on the above and recent advances, and review articles, particularly in regard to measurement, stress relieving technologies, prediction of distortion and the impact of residual stresses on product performance are invited for inclusion in this Special Issue on "Residual Stresses in Precipitation Hardened Aluminium Alloys".

This paper presents experimental and numerical investigations on the characteristics of residual stresses generated by induction heating (IH) on 12 mm thick steel plates. IH at 250 °C and 350 °C provided high tensile residual stresses in the heating field but high compressive stresses away from the heating field. The double heating case generated higher compressive residual stresses—around 200 MPa—than the single heating case because of the superposition of the compressive residual stresses. It will be expected to improve the fatigue performance of welded joints when IH is applied for repair work on existing steel structural members susceptible to fatigue damage. Numerical simulation models for predicting residual stresses by IH were proposed by adopting the body heat flux input and the surface heat flux input. They will be beneficial for identifying the optimum heating conditions, such as the target temperature and the heating field, for applying IH to the actual repair work of the steel structural members.

The reliability of welded structure can be evaluated through welding residual stress analysis and fatigue strength assessment. In this study, welding residual stresses of multi-pass dissimilar material welded joint between alloy 617 and 12Cr steel were analyzed numerically and experimentally. Fatigue strength was then assessed in the air. Based on results of welding residual stress analysis and fatigue strength assessment, a fatigue design method considering welding residual stress was investigated. Welding residual stresses at the weld of dissimilar welded joints distributed complicatedly on longitudinal and transverse directions, showing differences but a very similar distribution tendency between numerical and experimental results. Numerical and experimental peak values of welding residual stresses at HAZ of the weld on the 12Cr steel side were predicted to be 333 MPa and 282 MPa HAZ, respectively. The fatigue limit of dissimilar material welded joint between alloy 617 and 12Cr steel was assessed to be 306.8 MPa, which was 40% of tensile strength (767 MPa) of dissimilar material welded joint. However, the stress range including welding residual stress was assessed to be 206.9 MPa, which was 14% lower than that calculated by including the effect of residual stresses. Full article

The contour method is one of the newest techniques for obtaining residual stress fields from friction stir welded (FSW) parts, experimentally. This method has many advantages; however, edge effects coming from the process itself might introduce artifacts in the obtained results, and this was slightly touched upon in the very first paper on the method. This concern is further assessed in the present work, where the contour method is compared with the results that were obtained numerically via a thermomechanical model and experimentally via the cut-compliance method. For the two-dimensional (2-D) cross sectional map obtained by the method, peak stresses in tension are observed in the mid-section of the FSW butt-welded plates at the distance of the tool radius from the centerline. The corresponding numerical simulation indicates the same behavior because of the particular clamping conditions, and consequently this should not be interpreted as a misleading result of the contour method. Edge effects from the cutting process involved in the contour method should, however, be taken into consideration, most likely resulting in the residual stresses observed near the surfaces of the cross section being less extreme in reality than observed.

The influence from residual surface stresses on global indentation properties, i.e., hardness and size of the contact area, have been studied quite frequently in recent years. A fundamental assumption when evaluating such tests is that the material hardness is independent of any residual stresses. This assumption has been verified in the case of cone indentation of classical Mises elastoplastic materials. However, a detailed investigation of this feature in the case of three-dimensional indentation, i.e., Vickers and Berkovic indentation, has not been presented previously. It is therefore the aim of the present study to remedy this shortcoming using finite element methods. The numerical results pertinent to Vickers indentation clearly show that the material hardness is independent of residual (or applied) stresses (also in case of three-dimensional indentation problems). The limitations of the validity of hardness invariance are also discussed in some detail. Full article
