Abstract: | The recent research manages the creation and friction stir welding (fsw) of an aluminium metal lattice composite. Tib2, sic and b4c like ceramic particles are used to strengthen aa6061 grid metal. This fsw could be identified as a propelled welding process and it has been applied by in consolidating of various metals, flimsy and plastic sheets. Fsw is used to join aluminum based composites both similar and dissimilar types. It is totally environmental friendly process as no heat is generated nor transferred. Experimentation is performed in fsw machine introduced at iit madras. Various test trails are carried out over manufactured composites by changing the weight percentages of particulates. The rotational speed and transverse speed were selected to weld composite .the tool rotational speed are 500, 700 and 900 rpm while the values of transverse speed are 40, 50, 60 mm/min. The tool proposed in this research is of a cylindrical shape, the material is h-13 instrument steel oil solidified to 60 hrc. The fsw apparatus shoulder manufactured with the diameter of 24 millimeter and the tip inference is eight-millimeter. The final product of this investigation is given in two sections, focusing for the most part on end results of particles reinforcements on metallurgical and mechanical aspect of weldment composites. Tensile test, hardness test and microstructure characterization studies were conducted for welded composites. Tensile strength of friction stir welded composite is 250 mpa which is significantly greater than base metal aa6061. The ductility of the composite is 2.2%. The vickers hardness of sample 4 exhibits high hardness of 120hv. The sample 1 exhibit less hardness below 80hv. For the apparatus rotating pace 900 rpm and crosswise weld velocity 60 mm/min, the weldabilty of 92% has been gained for the proposed process parameter setting. The weldment quality increases ii With increasing rotational speed from 500 rpm to 900 rpm, further it decreases with its additional increase in tool rotational speeds. When |
