Influence of Process Parameters on Microstructure of Friction Stir Processed Mg AZ31 Alloy
Friction stir processing (FSP) has been developed on the principles of friction stir welding (FSW) as an effective and efficien new method for grain refinement and microstructural modification, providing intense plastic deformation as well as higher strain rates than other conventional severe plastic deformation methods. FSP produces an equiaxed homogeneous microstructure consisting of fine gra...
متن کاملAnalysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy
Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages. Laser Assisted Friction Stir Welding (LAFS...
متن کاملForming and Properties of Friction Stir Welding Process for Dissimilar Mg Alloy
For hot extrusions of magnesium alloy sheets, Dissimilar AZ80 and AZ31 were used, in which AZ80 was placed on advancing side and AZ31 on retreating side, using friction stir butt welding with different process parameters. Some defect-free welded joints with good weld surfaces could be obtained with some suitable welding conditions. The maximum tensile strength of welded joint which is 225.5 MPa...
متن کاملTHERMAL STABILITY OF FRICTION STIR PROCESSED ULTRAFINE GRAINED Al-Mg-Sc ALLOY
Two different aspects of the thermal stability of grains were studied – (i) thermal stability of grain structure evolution during friction stir processing (FSP), and (ii) thermal stability of grains after FSP. It was concluded that Al3(Sc,Zr) dispersoids are effective in limiting grain growth to ultrafine grained regime (UFG) by stabilizing the microstructure during FSP. The presence of these d...
متن کاملEffects of Process Parameters of Friction Stir Processing on Tensile Strength of AA6063 Aluminum Alloy
In this investigation, the effect of friction stir processing (FSP) parameters such as rotational speed, traverse speed and plunge depth on the tensile strength of AA6063 aluminum alloy was studied. The experiments were carried out as per response surface methodology parametric design concepts to study the influence of various combinations of process parameters. Statistical optimization techniq...
