The Strength of Friction Stir Welded and Friction Stir Processed Aluminium Alloys
Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...
متن کاملStudy of Mechanical Properties Change During Friction Stir Spot Welding of Aluminium Alloys
The Friction Stir Welding process is now 20 years old and the interest in it and its potential continues to increase dramatically. FSW can be applied to a multitude of products with varying material types and thicknesses. However, a continuous weld is not always required to meet the product performance requirements. Thus, one can consider some form of intermittent weld, such as Friction Stir Sp...
متن کاملEffect of Friction Stir Welding on Mechanical Properties of Dissimilar Aluminium Alloys
Friction stir welding is advance joining process for different similar and dissimilar metals. It is commonly used for joining of Aluminium alloys. In this study an attempt were made to join commercial structuralaluminium with 7039 aluminium alloy. A zig-zag pattern of hardness was found in weld nugget. Microstructural characterization and fractography of joints were examined using optical and s...
متن کاملInfluence of Friction Stir Welding residual stresses on the mechanical behaviour of aluminium stiffened panels
In this work, the longitudinal residual stresses that arise from FSW processes were measured by means of the Contour Method. These residual stresses were then introduced into a numerical simulation model based on the Finite Element Method (FEM), and their effect on the buckling collapse load of aluminium stiffened panels was assessed. The sensitivity of the models to initial geometrical imperfe...
متن کاملFatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
