“…One type of graph shows highest value of hardness in the stirred zone and its goes on decreasing along TMAZ and HAZ, and shows minimum value in the base material region as shown in Fig. 5 [24,26,27,31,[33][34][35]. Refinement of grain caused by dynamic recrystallization and proper distribution of particles due to the severe stirring action of FSW tool, results in higher hardness at the stirred zone.…”

Friction stir welding (FSW) is established as one of the prominent welding techniques to join aluminium matrix composites (AMCs). It is a solid state welding process, takes place well below the melting temperature of the material, eliminates the detrimental effects of conventional fusion welding process. Although the process is capable to join AMCs, challenges are still open that need to be fulfill to widen its applications. This paper gives the outline of the friction stir welding technique used to join AMCs. Effect of process variables on the microstructure and mechanical properties of the joints, behavior of reinforcing materials during welding, effect of tool profiles on the joint strength are discussed in detail. Few improvements and direction for future research are also proposed.

Friction stir welding (FSW) is a welding phenomenon where metals are plasticized and joint with suitable applied pressure. It is a solid state of welding process with non-consumable tool. Magnesium alloy materials like AZ31 and AZ91 are selected in this experimental work. Because, this alloys having low density as compare to steel so it is lighter in weights. Also this material are having good strength, ductility and corrosion resistance [21]. A taguchi approach along with design of experiment (DOE) methodology are used to optimize weld parameter. Rotating seed, transverse speed and materials are selected as a working parameter for experimentation. After a weld tensile test is used to determine different design parameter of different weld specimen.

The tools used in the process of friction stir welding wear gradually, which is one of the causes of joint defects. Instead of using expensive wear-resistant materials for tools, tool life can be extended by using antiwear tribological coatings. Due to huge development that has been observed in coating technologies, correct choice of a coating should be based on a series of tests in order to evaluate both mechanical and tribological properties. The aim of this study was to evaluate surface thickness and morphology and resistance to wear of commercial anti-wear coatings such as TiAlN, TiN, TiCN and AlCrN, deposited on hot work steel X40CrMoV5-1 as a base material. Examinations of coatings were conducted in order to explore potential opportunities for their use in tools, designed for the process of friction stir welding of aluminium alloy 7075 T6 to improve tool life. The scratch test method was used to evaluate the adhesiveness of coatings to the base material. Tribological properties of the examined coatings were evaluated based on the results of the examinations obtained on T-01 pin-on-disc tester and T-05 block-on-ring testers. The results of tribological tests conducted under dry friction conditions demonstrated that the highest resistance to abrasive wear among the coatings examined was found for the AlCrN.
