Az31b Alloy

Friction stir processing (FSP) is an emerging surface modification technology for enhancing the sheet metal properties through microstructural refinement at a particular region which might undergo severe plastic deformation. The extruded AZ31B magnesium alloy used in this investigation exhibits very limited ductility accompanied by brittle like behavior at room temperature because of hexagonal packed structure and severe mechanical twinning. Hence, an attempt was made to study the effect of processing parameters such as tool rotational speed and tool traversing speed on tensile properties of friction stir processed AZ31B magnesium alloy. It is found that the friction stir processing of the Magnesium alloy improved the ductility of the material when compared to the base material and also produced an ultrafine equiaxed grain in the processed zone, an ideal condition for the material to exhibit superplasticity.

Abstract This research focused on developing a hybrid quality monitoring model through combining the data driven and key engineering parameters to predict the friction stir blind riveting (FSBR) joint quality. The hybrid model was formulated through utilizing the in-situ processing and joint property data. The in-situ data involved sensor fusion (force and torque signals) and key processing parameters (spindle speed, feed rate and stacking sequence) for data-driven modeling. The quality of the FSBR joints was defined by the tensile strength. Further, the joint cross-sectional analysis and failure modes in lap-shear tests were employed to confirm the efficacy of the proposed model and development of the process-structure-property relationship.
