Friction stir processing (FSP) is solid state novel technique developed to refine microstructure and to improve the mechanical properties and be used to fabricate the aluminium alloy matrix composites. An attempt is made to fabricate AA6061/TiB2 aluminium alloy composite (AMCs) and the influence of process parameters like rotational speed, transverse feed, axial load and percentage reinforcement on microstructure and mechanical properties were studied. The microstructural observations are carried out and revealed that the reinforcement particles (TiB2) were uniformly dispersed in the nugget zone. The Tensile strength and Hardness of composites were evaluated. It was observed that tensile strength, and hardness were increased with increased the rotational speed and percentage reinforcement of particles. The process parameters were optimized using Taguchi analysis (Single Variable) and Grey analysis (Multi Variable). The most influential parameter was rotational speed in single variable method and multi variable optimization method. The ANOVA also done to know the percentage contribution of each parameter

“…It is observed that the ultimate tensile value increases with respect to forge stress increase up to some optimum value and then it start decreasing, for both combinations and the weld strength totally dependent on Spindle Speed and forge stress. Handa et al [14] had studied the mechanical properties of weld joints between AISI 304 and AISI 1021 steels fabricated with FW technique. The main variables considered were Spindle Speed (920 RPM) which remain constant and range of axial stress (75, 90, 105, 120, 135 Megapascal).…”

Friction welding (FW) is a solid state welding method invented in 1940s by the welding institute. Without genuine liquefying of the materials, a normally excellent weld joint is produced with this procedure. The method is quick, environment friendly and easy to carry out. The extent of the present examination is to assess the effect of welding variables on the tensile properties of friction welded of dissimilar metals. From this review study, posted research papers of different authors has been studied and it has been determined that the welding variables like revolution pace, rubbing time , friction stress, forge time, forge strain are have high impact on the mechanical properties of friction welded joints. Finally, the conclusions of the review study presented the practical applications for the manufacturing sector and proposals for further innovative work and advancements. The purpose for this article is to advise industry and the scholarly world regarding the advantages of rotary FW so the procedure might be used in better way.

Friction Stir Welding (FSW) of an Al-13%Si alloy matrix reinforced with 0, 3 and 6 wt% Al2O3 nanoparticles (nAl2O3) is performed and the optical microstructures, tensile strength, hardness and sliding wear properties of friction stir welded joints are investigated and compared to those of base materials. Four different zones of distinct appearances were observed during FSW, which exhibited altered microstructures in the nugget zone (NZ), thermo mechanically affected zone (TMAZ), heat affected zone (HAZ), and base material zone (BMZ). The ultimate tensile strength of the base materials and their welded joints were found to be increasing with increased wt% of nano-alumina reinforcements. High joint efficiency of 89-97% was achieved in FSW. Hardness and wear resistance of friction stir welded joints were found to be better than those of the base materials. KEYWORDS:Friction stir welding, Metal matrix composite, Mechanical properties, Al-Si alloy, Alumina, Wear IntroductionVarious hard micro/nanoscale ceramic particle reinforced aluminium matrix composites are among the most widely studied metal matrix composite materials owing to their excellent material properties such as high specific strength and stiffness, low density, low thermal expansion and enhanced creep and wear resistance. The widespread usage of these metal matrix composites with the advancements of various ceramic particles is severely limited due to inadequate and inefficient secondary processing or manufacturing techniques such as machining and welding. The Welding Institute (TWI) UK [1] patented a solid-state joining method "friction stir welding" which has been used widely to produce high quality welds in many materials like aluminium, nickel, magnesium, titanium and steel for applications in automobiles Friction stir welding has an advantage over fusion welding of metal matrix composites owing to the absence of any kind of segregation and/or reaction to the reinforcements, hot cracking and porosity during the solid phase welding process. Al-Si alloy is one of the most popular materials for aerospace, automobile, and marine industries due to its high fluidity and castability, low density, high specific strength and good corrosion properties [13,14]. Silicon is known for reducing thermal expansion and increasing wear and corrosion resistance of the alloy [15]. Ceramic reinforcements further improve the wear resistance properties of Al-Si alloys. Absence of melting in FSW diminishes the probability of defect formation and recovers the mechanical properties which enable FSW a capable joining method for metal matrix composites (MMCs). Several studies have been performed on FSW of micro-sized alumina Unauthenticated Download Date | 5/11/18 1:43 PM
