In this study, linear friction welding (LFW) is used to join high carbon steel such as S55C (JIS G 4051) because it controls the maximum temperature during the joining process. The effect of LFW conditions on Charpy absorbed energy is studied. The thickness of a rectangular parallelepiped shape is 14 mm, the width is 20 mm, and the length is 64 mm. The applied pressure (P) controls the maximum temperature. Under high-temperature conditions, P is 100 MPa. Under middle-temperatures conditions, P is between 250 and 350 MPa. Under low-temperature conditions, P is between 400 and 450 MPa. Under all condi-tions, joints are cooled to room temperature. The microstructure and hardness of LFW joints are examined. The toughness is determined using a 300 J instrumented Charpy tester. The absorbed energy is estimated using two methods. The first method uses the potential energy difference, and the second involves calculating the area surrounded by the stroke-load relationship. With an increase in P, the microstructure changes from martensite to ferrite and microcementite. In addition, the maximum hardness at the interface decreases from 500 HV-700 HV to 400 HV. The maximum absorbed energy is confirmed at 400 MPa using the potential energy method and at P of 450 MPa using the area method. Energies absorbed before and after the maximum load are assumed to be crack initiation and propagation (E p ) energies, respectively. The maximum ener-gy is due to an increase in E p , which is enhanced when the microstructure changes from martensite to ferrite and microcementite.

“…The strength increase can be accounted mainly to the presence of nickel which reduces the creation of inter-metallic in the weld section. Handa et al [20] had evaluated the fracture behavior and ultimate tensile value of welded joints between AISI 304 and AISI 1021 steels fabricated with FW procedure at Spindle Speeds (800, 1000, 1250, 1430, 1600 RPM) and range of axial stress (75, 90, 105, 120, 135 Megapascal). To evaluate the welded joints, various tests like tensile strength, fractography test and micro hardness test were conducted.…”

Friction welding (FW) is a solid state welding method invented in 1940s by the welding institute. Without genuine liquefying of the materials, a normally excellent weld joint is produced with this procedure. The method is quick, environment friendly and easy to carry out. The extent of the present examination is to assess the effect of welding variables on the tensile properties of friction welded of dissimilar metals. From this review study, posted research papers of different authors has been studied and it has been determined that the welding variables like revolution pace, rubbing time , friction stress, forge time, forge strain are have high impact on the mechanical properties of friction welded joints. Finally, the conclusions of the review study presented the practical applications for the manufacturing sector and proposals for further innovative work and advancements. The purpose for this article is to advise industry and the scholarly world regarding the advantages of rotary FW so the procedure might be used in better way.

“…18 In the past decade, a lot of research work has been done utilizing friction stir welding and FSP. [19][20][21][22] However, recent studies have proven that developing a Mg-based composite through hybrid reinforcement and FSP is a viable choice for achieving enhanced mechanical properties and improved performance in lightweight materials. 23,24 Compared to mono-reinforced composites, this approach offers the advantage of combining multiple reinforcements, leading to synergistic effects, increased strength, and tailored properties for specific applications.…”

Low-cost hybrid-reinforced magnesium metal matrix composite (HMMC) materials present a revolutionary category of materials achieved by combining two or more distinct reinforcing elements within the magnesium (Mg) matrix. The main focus of this research is to fabricate Mg-based HMMCs with exceptional mechanical and other characteristics by utilizing Mg substrate AZ61A as the base material. To achieve this, nano-titanium carbide (TiC), nano-silicon carbide (SiC), and fly ash (FA) were selected as hybrid reinforcements, and the friction stir processing technique was employed for their incorporation. The microstructural, thermal, mechanical, wear, and fracture properties of synthesized HMMCs were carefully examined using a conventional testing approach. The findings demonstrate that the grain size of the base AZ61A alloy was measured at 32 µm, whereas the AZ61A/FA/TiC/SiC composite exhibited a remarkable reduction to 3.5 µm. Notably, this reduction in grain size leads to simultaneous enhancement in mechanical properties. The microhardness, ultimate tensile strength, and ultimate compressive strength of the developed HMMC showed an impressive increase, measuring 2.09 times, 2.75 times, and 2.10 times higher, respectively, compared to their initial values of the base material. Moreover, a significant enhancement in wear resistance was also observed, attributed to the increased hardness and homogenous hybrid reinforcement dispersion into the HMMCs. In addition, it was evident that the synergistic combination of different reinforcement particulates in Mg-based alloy improves overall fracture resistance and catastrophic failure and mitigates crack propagation.
