“…It is likely that this phenomenon is related to the formation of deformation-induced boundaries and the subsequent accumulation of misorientation angles. Previous studies on friction stir welding and friction surfacing of aluminum alloys [42,44,46] have interpreted progressive boundary movement like this in terms of continuous rather than discontinuous recrystalization. From the present data, it is likely that continuous recrystallization plays an important role in the development of the microstructure of the rivets during the FricRiveting process.…”

“…On the basis of the microstructural characteristic, this area was classified as the metal friction zone (MFZ). Presence of the friction zone has also been proposed in the friction surfacing of an aluminum alloy AA6082-T6 rod on an aluminum alloy AA2024-T351 substrate [42]. Both processes are similar, in that the consumable material or rod (or rivet, in the FricRiveting case) is rotated at high speed under pressure, rubbing the substrate surface and producing frictional heating at the contact surface between the rod end (or rivet tip) and the substrate surface.…”

Friction surfacing (FS) is an advanced solid state process in surface modification with increasing applications in reclaiming worn parts, hardfacing and corrosion protection. The advantages of the process are that materials are deposited in the solid state and the resultant forged microstructure which leads to enhanced mechanical properties. As no melting takes place, the process allows joining of dissimilar materials while avoiding several fusion related problems. The present study addresses the deposition of AA5083-H112 coatings over AA2024-T3 substrates focusing on the influence of the main process parameters such as axial force, rotational speed and deposition speed, in the mechanical properties of the deposits. A performance and geometric analysis of the depositions are also presented. Sound aluminum coatings were produced; plastic deformation and heat generation promotes a dynamic recrystallization of the anisotropic consumable rod, resulting in a fine and homogeneous deposit. The coating presented an increase in ultimate tensile strength and failure deformation of 9% and 6%, respectively. Deposition efficiency between 25 and 50% were obtained, with a maximum of 48% average efficiency observed with 800 RPM, 12 kN and 16 mm/s.

“…Rafi et al 6 showed the microstructural evolution occurring in H13 steel, while Vilaça et al 12 showed the microstructural transformation in a consumable rod during FS. Gandra et al 13 obtained a refined microstructure with a degree of refinement of 33% after a FS process, Puli 14 related the dynamic recrystallization phenomenon during FS for a austenitic stainless steel and Suhuddin et al 15 made a brief investigation of dynamic recrystallization of AA6086-T6 during FS.…”

The aim of this work was to produce deposits of AA6351-T6, reinforced with alumina (Al 2 O 3 ) particles, over a substrate of AA5052-H32 through friction surfacing. AA6351-T6 consumable rods were drilled with one and two holes, which were filled with Al 2 O 3 particles posteriorly. To perform the deposition, a conventional KONE KFE-3/BR milling machine was used. The results showed that Al 2 O 3 particles increase the hardness values of the produced deposits when compared to those without particle addition. The coatings presented a fine equiaxed grain size distribution, once the grain refinement was nearly 48% lower than the as-received material. Moreover, deposit regions that showed finer grain boundaries also showed a higher volume fraction, which can be related to the particle stimulated phenomenon. Electron backscatter diffraction results showed the occurrence of low angle grain boundary substructures and lattice rotation, indicating that the material undergoes dynamic recrystallization during friction surfacing.
