“…For the nanocomposite layer, the presence of nanoparticles improves hardness and material strength against plastic deformation and reduces the adhesion between the wear disc and pin [25,26]. The nanocomposite has a lower weight loss than as-received Cu, FSPed Cu, and microcomposites.…”

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.

“…It is also observed that the composite is bonded well with the aluminum matrix on all the sides. During FSP, the particles were homogeneously distributed in the aluminum matrix due to the intense stirring action of the tool [27,29].…”

In this work, friction stir processing (FSP) has been employed to fabricate metal matrix composites by incorporating B 4 C reinforcement particles into the aluminum AA6061 matrix. Taguchi experimental design, consisting of three factors and three levels, is used for minimizing the number of experiments. The factors considered are tool rotational speed, traverse feed and tool tilt angle. Desirability function analysis was employed to optimize the FSP parameters for simultaneous improvement of tensile strength and microhardness of the composites. The optimal parameters were found, and it was confirmed by experimental results. The composites fabricated using optimal process parameters exhibit a higher tensile strength (174 MPa) and microhardness (183 Hv). The tensile strength and microhardness values observed have been correlated with microstructural studies. Scanning electron micrograph revealed defect-free fabricated composites and uniform distribution of reinforcement particles in the stir zone.

“…rotation speed and pass number, significantly influence the microstructure of the processed materials. Increasing pass number during FSP can refine grains due to severe plastic deformation experienced and severe stirring effect in stir zone, which significantly optimized surface properties [26]. Multiple-pass FSP with a 100% overlap was reported to be an effective approach to achieve refined and homogeneous microstructure in as-cast AZ91 [27].…”

Microstructure evolution and superelastic behavior in Ti-35Nb-2Ta-3Zr alloy processed by friction stir processing

This work investigates systematically the phase transformation and superelasticity in TiNbTaZr alloy prepared by friction stir processing (FSP). Multiple-pass FSP with a 100% accumulated overlap to three passes was implemented. The influence of the processing parameters on the microstructural evolution and superelasticity in stir zone, transition zone, and heat affected zone were investigated. After recrystallization, existing dislocations gradually accommodate themselves at sub-grain boundaries. Increase in the proportion of α″ martensitic phase is always accompanied by significant reduction in the fraction of ω phase precipitation. Metastable ω phase dissolving feature is evident and promoted by dislocation gliding, especially in the specimen processed at a higher rotation speed. In nanoindentation measurements, the closer the indent applied towards the transition zone, the more martensites nucleate, thereby gradually reducing both elastic modulus and hardness via re-orientation of martensites. This study provides new insight into the surface modification of beta titanium alloys through FSP method to achieve improved mechanical properties
