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 کاملTensile properties and fracture locations of friction-stir-welded joints of 2017-T351 aluminum alloy
Friction stir welding (FSW) is a new and promising welding process that can produce low-cost and high-quality joints of heat-treatable aluminum alloys because it does not need consumable filler materials and can eliminate some welding defects such as crack and porosity. In order to demonstrate the friction stir weldability of the 2017-T351 aluminum alloy and determine optimum welding parameters...
متن کاملRole of Delamination and Crystallography on Anisotropy of Charpy toughness in API-X80 steel
The orientation dependence of Charpy toughness has been investigated in API-X80 linepipe steel. The occurrence of delamination and preferential alignment of {100} cleavage planes are found to contribute to the observed anisotropy in Charpy properties. Delamination is also related to the presence of banding in the hot–rolled alloy, and the additional plasticity it entails during the process of f...
متن کاملFriction-Stir-Processing Effect on Fracture Toughness of Oil Pipelines in ST 37 Group Before/After Nano ZrO2-Coating
Herein, Compact-Testing (CT ) and Charpy V-Notch (CVN) testing have been done on four Friction-Stir-Processed (FSPed) samples: BM (Base-Metal), FS (FSPed-Sample), FN5 (FSP Nano-ZrO2-coated/560 rpm rotational speed) and FN9 (FSP Nano-ZrO2-coated/900 rpm), to investigate the KIC and the dominant parameters on it for St 37 steel. Experiments are also surveyed and validated by ABAQUS. Results showe...
