Abstract In friction stir welding process heat generation in the welding zone is most common due to the friction in between the tool and the weldment. When the heat concentration in the weld zone, then the flow of heat through the tool as well as in the weldment. It is requisite to dissipate the heat in order to weld continuously and to increase the weld distance. It is up to the tool design and tool profiles. By doing the thermal simulation in the tool, the tool temperature distribution and compare the number of tools with respect to temperature and able to finalize the tool which has maximum heat dissipation. In this work, 3 tools are designed in total with a pentagon pin profile with different volumes. Which is modeled in solid works software and converted into the Ansys file, then the material properties to be selected, each tool has different materials. Then it gives the corresponding mesh size and boundary conditions such as Temperature, Convection, etc. The tool has been mesh and found out the solution for all tools. As a result, it is found that tool number 1 has a maximum heat dissipation.

Abstract The effect of cutting performance was investigated using uncoated plain andtextured tungsten carbide tools in dry machining of carbon steel. Texture namely straight line,zigzag and plus profiles was created on flank face of the uncoated tungsten carbide tool. This textured tool was designed and fabricated by Neodymium-doped Yttrium Aluminium Garnet ND-YAG laser machine. Also it was evident with scanning electron microscopy analysis. In further design of experiment was carried by taguchi method by using L9 orthogonal array for varying cutting speed, feed rate, depth of cut to perform the machining experiment. The cutting force,surface roughness and cutting temperature were measured in which it depicts that microscale textured tools improves the machining characteristics to a greater extent when compared with untextured tool. It can be effective in all manufacturing industries provide an eco friendly environment since no coolant is required due to which it becomes pollution free.

Friction stir welding, a novel semi-solid state welding process, has been constantly evolving technology since 1991. In this work friction stir welding was carried out on aluminium metal matrix composites reinforced with SiC and ZrB2. The influence of tool profile and material on the strength of weldment was studied. Plain pentagon, plain tapered and threaded cylinder tool made of materials such as OHNS, HCHCr, and H13 with varying D/d ratios were used. The friction stir welded specimens were subjected to mechanical and metallurgical characterization. Threaded cylinder profiled tool made of H13 steel with a D/d ratio of 2 yielded weld joints of highest strength. Weld zone microstructure of the Al-10% ZrB2 MMC and Al-10% SiC welded using H13 threaded cylinder tool exhibited considerable grain refinement with the precipitates homogeneously distributed.

Friction Stir welding is a solid state joining process with no filler material. In this work, we specifically investigated the Tool Pin Profile, Tool Material, Base Material and the process parameters in the Aluminum metal matrix composites especially reinforced with Zirconium diboride (Al–ZrB2 . Tools of Various Materials and the corresponding tensile strength of the weld specimen, microstructure analysis and Hardness test are evaluated. Threaded Cylinder made of various materials are OHNS, HCHCr, H13 tools are carried out in the process with D/d Ratio are used. The result will be stated with the Threaded Cylinder pin with which tool material provides highest strength to the Bas material.

The aim of this research is to fabricate aluminum based metal matrix composite and reviewing its tensile strength and wear behavior of produced test specimen. In this work an attempt is made to develop an aluminium based MMCs with reinforcing material and stir casting technique has been used to achieve this. Aluminum alloy (LM6) and Magnesium (Mg), Copper (Cu) was chosen as metal matrix and composite materials respectively, tensile and wear experiments has been conducted by varying the composition of Cu (0.150%, 0.175% and 2%) while keeping Mg (0.150%) as constant. The result shows that the increase in addition of copper increases the tensile strength and wears resistance and decreases the percentage of elongation.
