Friction Stir Welding of Extruded Powder Metallurgy Al Alloy

  title={Friction Stir Welding of Extruded Powder Metallurgy Al Alloy},
  author={A. Elrefaey and K. Anders and H. Kilian and F. Ellermann},
Friction stir welding (FSW) of an extruded powder metallurgy (PM) aluminum alloy was performed to produce a rotary engine housing. The mi­ crostructure, phase constituents, and mechanical properties of FSW joints were studied by metallography, tensile, and fatigue tests. The results indicated the process achieved sound joints without voids or discontinuities. The mi­ crostructure of welded area (stir zone) was finer and more homogeneous than the base metal, while the average yield strength… Expand
Electron backscattered diffraction analysis of friction stir processed nanocomposites produced via spark plasma sintering
The results revealed that the heat generated during FSP has a remarkable effect on the grain distribution as well as on the crystallographic orientation. Expand


Friction Stir Welding and Processing
Abstract Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used toExpand
Characterization of aluminum/steel lap joint by friction stir welding
The welding of a lap joint of a commercially pure aluminum plate to a low carbon steel plate (i.e., Al plate top, and steel plate bottom) was produced by friction stir welding using various rotationsExpand
