“…1 This process has been applied to microstructural modifications for enhanced mechanical properties through intense plastic deformation using a non-consumable rotating tool that causes material mixing and thermal exposure and results in grain refinement of the material being processed. 2,3 The benefits of the FSP process include significant microstructural refinement, densification, and homogeneity of the processed zone, homogenization of precipitates in various aluminium alloys and composite materials. [4][5][6] Moreover, the severe plastic deformation (SPD) and material flow in the stirred zone of the FSP can be utilized to achieve surface or bulk alloy modification by the mixing of other elements into the stirred alloys where the stirred material can become a metal matrix composite or an intermetallic alloy with much higher hardness and good wear-resistance properties.…”

“…They analysed the microstructure and microhardness of the fabricated AMC and from their results, revealed a uniform distribution of TiC particles which were well bonded to the matrix alloy with an increase in the hardness value of the AMC compared to that of the matrix alloy. E. Akinlabi et al 3 investigated the effect of the processing parameters on the wear-resistance behaviour of friction-stir processed Al-TiC composites. From their findings it was revealed that an increase in the hardness value, which was a function of the TiC particles incorporated when compared to the parent material and the wear resistance property, was also found to increase as a result of the TiC powder addition.…”

In this study the friction-stir processing (FSP) technique was applied for the development of surface composites of aluminium alloy (AA 1050) reinforced with titanium carbide (TiC) powder of particle size range below 60 μm compressed into the groove. Rotational speeds of 1200 min -1 and 1600 min -1 and the travel rates of (100, 200 and 300) mm/min were used for the process. This study investigates the effect of processing parameters on the wear-resistance behavior of friction-stir processed Al-TiC composites. This was achieved through microstructural characterization using optical and scanning electron (SEM) microscopes equipped with Oxford energy-dispersion spectrometry (EDS) (Tescan), microhardness profiling and wear resistance tests. From the results, it was found that the processing parameters influenced the distribution of the TiC particles. The microhardness profiling of the processed samples revealed an increase in the hardness value compared to the parent material. The wear-resistance test results confirmed the FSP technique enhanced properties in surface engineering. Keywords: aluminium alloy, friction-stir processing, microhardness, microstructure, surface composite, TiC V {tudiji je bila uporabljena tehnika me{anja s trenjem (angl. FSP) za razvoj povr{inskih kompozitov iz aluminijeve zlitine (AA 1050), oja~anih s titanovim karbidom (TiC) v prahu, z velikostjo delcev v obmo~ju pod 60 μm, stisnjenih v utor. Pri tem postopku so bile uporabljene hitrosti vrtenja 1200 min -1 in 1600 min -1 in hitrosti pomikanja (100, 200 in 300) mm/min. [tudija raziskuje vpliv procesnih parametrov na odpornost kompozitov Al-TiCi proti obrabi s trenjem. Izvedena je bila mikrostrukturna karakterizacija z uporabo svetlobnega in vrsti~nega elektronskega mikroskopa (SEM), opremljenega z Oxford energijsko disperzijsko spektrometrijo (EDS) (Tescan), profiliranja mikrotrdote in preizkusa obrabe. Iz rezultatov je bilo ugotovljeno, da so parametri obdelave vplivali na distribucijo TiC delcev. Profiliranje mikrotrdote na vzorcih je pokazalo, da je vrednost trdote pove~ana v primerjavi z osnovnim materialom. Rezultati testa odpornosti obrabe so potrdili, da FSP-tehnika izbolj{a lastnosti povr{ine.

A study was conducted on the material characterization of aluminium (Al) and titanium carbide (TiC) metal-matrix composites produced via friction stir processing. Different process parameters were employed for the welding process. Rotational speeds of 1600 min -1 to 2000 min -1 , at an interval of 200 min -1 and traverse speeds of 100 mm/min to 300 mm/min, at an interval of 100 mm/min were employed for the welding conducted on an Intelligent Stir Welding for Industry and Research (I-STIR) Process Development System (PDS) platform. The characterizations carried out include light microscopy and the scanning electron microscopy analyses combined with Energy-Dispersive Spectroscopy (SEM/EDS) techniques to investigate the particle distribution, microstructural evolution and the chemical analysis of the welded samples. Vickers microhardness tests were used to determine the hardness distribution of the welded zone and tensile testing was conducted to quantify the strength of the welded area compared to the base metal in order to establish the optimal process parameters. Based on the results obtained from the characterization analysis, it was found that the process parameters played a major role in the microstructural evolution. A homogenous distribution of the TiC particles was observed at a high rotational speed of 2000 min -1 and a low traverse speed of 100 mm/min. The highest hardness value was measured at the stir zone of the weld due to the presence of the TiC reinforcement particles. The tensile strength also increased as the rotational speed increased and 92 % joint efficiency was recorded in a sample produced at 2000 min -1 and 100 mm/min. The EDS analysis revealed that Al, Ti and C made up the composition formed in the stir zone. The optimum process parameter setting was found to be at 2000 min -1 and 100 mm/min and can be recommended.
