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

“…Considering the second-phase particles as sites of void creation, the nucleation sites for voids will increase when the particles are dispersed. Therefore, the dimples will be created in smaller sizes and join the adjacent voids before growing to larger sizes [54]. Besides, the smaller grain size of the matrix also contributes to the shallower dimples [55].…”

Abstract:In this work, a fine-grained structure with a uniform distribution of TiB 2 particles and precipitates was achieved in TiB 2 particle-reinforced (PR) Al-Zn-Mg-Cu alloys by friction stir processing (FSP). The effects of multi-pass FSP on the microstructure, and TiB 2 particle distribution, as well as the microstructural evolution in the following T6 treatment, were investigated by X-ray diffraction, scanning electron microscopy and associated electron backscattered diffraction. The results showed that the distribution of TiB 2 particles and alloy precipitates was further improved with an increase in the FSP passes. Moreover, compared with alloy segregation in the as-cast PR alloys during T6 treatment, a complete solution of the precipitates was achieved in the FSP-treated PR alloys. The fine-grained structure of the FSP-treated PR alloys was thermally stable without any abnormal growth at the high temperature of T6 treatment due to the pinning effect of dispersed TiB 2 particles. The strength and ductility of the PR alloys were simultaneously improved by the combination of FSP and T6 treatment.

“…(c) Orowan strengthening mechanism was due to effective bonding and dispersion of ceramic particles with matrix material [21]. (d) Decreasing direct load contact between the Cu/SiCp microcomposite and nanocomposite surfaces (pin) and the steel (disc) was because of load bearing component action of hard SiCps [9,22]. Figure 7 shows the change in friction coefficients over time for a sliding distance of 500 m for different samples.…”

“…Barmouz et al [9] produced Cu/SiC surface composites using micron-sized SiCps via FSP using different process parameters to enhance the surface properties of the composites. Higher traverse speeds resulted in poorer dispersion of SiCps and consequently reduced the microhardness values of MMC layers.…”

Abstract:In this study, microsized and nanosized silicon carbide particles (SiCps) were successfully incorporated into commercial pure copper to form a surface metal matrix composite by friction stir processing (FSP) at low-heat-input conditions. A cluster of blind holes on a copper plate was used as particle deposition technique during the fabrication of the composite. Pin-on-disc testing was performed under dry sliding conditions to determine the wear characteristics of prepared composite surfaces. The homogeneity of particle distribution both inside the copper matrix and in the wear scar was determined via microstructural observations. It was observed that both microsized and nanosized SiCps were well distributed and homogenous in a stir zone; particles observed were without defects, and good bonding was observed between SiCps and the copper matrix. Comparisons between Cu/SiCp composite layers and friction stir processed (FSPed) Cu and as-received Cu showed that Cu/SiCp nanocomposite layers exhibited superior microhardness and dry sliding wear characteristics.
