Öğe Friction welding of dissimilar AISI 304 and AISI 8640 steels(European Journal of Technique (EJT), 2016-08-01) Batı, Serkan; Kılıç, Musa; Kırık, İhsanThis study investigates the joinability of AISI 8640 heat treatable steel and AISI 304 austenitic stainless steel combined with friction welding. These steels have completely different properties and widely used in industrial applications. Welding is applied on steels with the parameters of 1800 rev/min turning speed, 50 MPa friction pressure and 2, 4, 6, 8 and 10 sec friction time by using continuously driven friction welding machine. After the welding process, tensile and hardness testing applied to determine tensile and hardness strength of welded samples. Additionally, in order to determine the microstructural features, research using the optical microscope, scanning electron microscope (SEM) with Energy-dispersive Xray spectroscopy (EDS) analysis tests were done. According to the information derived from the results, AISI 304 and AISI 8640 steels joined with friction welding without any problemÖğe Microstructure and mechanical properties of armor 500/AISI2205 steel joint by friction welding(Journals & Books, 2017-08) Batı, Serkan; Kırık, İhsan; Sarsılmaz, FurkanThis paper discussed the properties of friction welded joint of Armor 500 steel and duplex (ferritic/austenitic) steel AISI 2205 and compared the properties of weld at different welding parameters. The experimental study was conducted with the welding parameters such as friction pressure and friction time. The experimental results indicated that armor 500 steel could be joined to AISI 2205 steel using the traditional friction welding technique. The processed joints were tested through axial tension test. In addition, the highest tensile strength, which is 1020 MPa is obtained when friction time is 8 s and friction pressure is 80 MPa. The microstructures of the alloys and fracture surfaces were examined by optical and scanning electron microscopy. Experimental results indicate that microstructural and mechanical properties are significantly affected by changing welding parameters within the chosen range of conditions.Öğe Friction welding of dissimilar AISI 304 and AISI 8640 steels(Dicle Üniversitesi, 2016) Batı, Serkan; Kılıç, Musa; Kırık, İhsanThis study investigates the joinability of AISI 8640 heat treatable steel and AISI 304 austenitic stainless steel combined with friction welding.
