“…Therefore, extremely fine equiaxed grains were formed in the ferrite and pearlite structure. Moreover, martensitic structure can be seen in this region when the welding interface has reached above A 3 temperature accompanied by rapid cooling [20]. Therefore, the microstructure of AISI1060 steel was transformed to austenite.…”

Rotary Friction welding is one of the most popular methods of joining similar and dissimilar materials. It is widely used with metals and thermoplastics in a wide variety of aviation, transport and aerospace industrial component designs. This study investigates the influence of friction and upsetting pressures on the hardness, tensile properties and microstructure of the welds. The experimental results showed that as the friction and upsetting pressures increased, the hardness and tensile strength values increased, as well. The tensile fracture of welded joint occurred in the AISI 1060 side. The friction processed joints were evaluated for their integrity and quality aspects by optical and scanning electron microscopy. For the perfect interfacial bonding, sufficient upsetting and friction pressures are necessary to reach the optimal temperature and severe plastic deformation to bring these materials within the attraction range.Keywords: Welding, Mechanical properties, MicrostructureZgrzewanie tarciowe jest jedną z najbardziej popularnych metod łączenia podobnych i odmiennych materiałów. Jest ono powszechnie stosowane do łączenia metali i tworzyw termoplastycznych w szerokim zakresie wzorów części przemysłowych w lotnictwie, transporcie i przemyśle kosmicznym. Celem badań jest określenie wpływu tarcia i nacisków na twardość, właściwości wytrzymałościowe i mikrostrukturę spoiny. Wyniki doświadczalne wykazały, że zewzrostem tarcia i nacisków wzrosła twardość i wytrzymałość na rozciąganie. W trakcie prób rozciągania pękanie następowało po stronie stali AISI 1060. Zgrzewane tarciowo spoiny zostały oceniopne pod względem ich integralności i jakości za pomocą mikroskopii optycznej i skaningowej mikroskopii elektronowej. Dla uzyskania idealnego złączenia materiałów potrzebne są odpowiednie naciski i tarcie, aby osiągnąć optymalną temperaturę i intensywne odkształcenie plastyczne.

“…5), which could be explained by FW-induced dynamic recrystallization. In general, the FW process is accompanied by plastic ow, which makes the welded material potentially capable of accumulating and storing energy through simultaneous recrystallization of nuclei 18,19) . In addition, the values of the friction heat released during welding (around 0.5-0.6 T m ) were high enough to initiate the recrystallization of the welded material directly observed in this study (as indicated by the fractions of high-angle grain boundaries of over 79% for both materials; see Fig.…”

The microstructures and mechanical properties of lightweight friction-welded dissimilar materials such as A6063 and A2017 alloy rods were investigated in this study. Friction welding was performed at a rotation speed of 2,000 RPM, friction load of 12 kgf/cm 2 , and upset force of 25 kgf/cm 2 . After welding, grain boundary characteristic distributions and the formation of intermetallic compounds were analyzed by electron backscattering diffraction and transmission electron microscopy, respectively, while the mechanical properties of the welded materials were studied by Vickers microhardness and tensile testing. The obtained results revealed that the friction welding of the two alloys led to signi cant grain re nement from around 50 μm for the base materials to 2 μm for the welded zone, while the Vickers microhardness and tensile strength of the welded area were equal to 81% and 96% of the corresponding values for the base materials, respectively, owing to the formation and growth of intermetallic compounds. However, the fracture initiated in the A6063 base material during tensile testing indicated superior quality of the welded joint. Therefore, friction welding of dissimilar materials can be effectively used to produce joints with high durability.
