Öğe Sürtünme karıştırma kaynağı ile birleştirilmiş AA5182/AA5182 alüminyum alaşımlarının mekanik ve mikroyapı özeliklerinin belirlenmesi(Batman Üniversitesi, 2018) Batı, Serkan; Çetkin, Edip; Demir, FatihÖğe CR takviyeli NİAL/Nİ3AL fonksiyonel derecelendirilmiş malzemenin mikroyapı incelemesi(Fırat Akademi A.Ş, 2017) Batı, Serkan; Kılıç, Musa; Biliz, İbrahim; Demir, Fatih; Akan, Ayşenur AslıÖğe 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. 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 X-ray 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 problemsÖğe Production of intermetallic FGM(Dicle University, 2016) Batı, Serkan; Kılıç, Musa; Kırık, İhsanNiAl and NiTi intermetallic materials are among advanced technology materials that have outstanding mechanical and physical properties for high temperature applications. Particularly, creep resistance, low density and high hardness properties stand out in such intermetallics. It is known that Ni-Al intermetallics are commonly used in various application fields with the addition of Ti for improving properties there of (in terms of low density, high hardness and shear strength) in the produced intermetallics. In this study, with different features -325 mesh Al, Ni and Ti powders are mixed to form NiTi, Ni3Al and NiAl in atomic ratio. Sintering process was used in this study by adding different amounts of powder mixture. The mixed powders were pressed at a pressure of 100 MPa in a metal die at room temperature. Three important intermetallic compounds were produced by SHS method, by using different process parameters to obtain functionally-graded materials having different features of NiAl, Ni3Al and NiTi alloys. Analyses were conducted metallographically on the samples after producing, face propagation were calculated and hardness were determinedÖğe Ni-Al-B toz karışımından kendiliğinden ilerleyen yüksek sıcaklık sentezi yoluyla gözenekli malzeme üretilmesi(Batman Üniversitesi, 2018) Batı, Serkan; Çetkin, Edip; Demir, FatihÖğe Kendi ilerleyen yüksek sıcaklık sentezlenmesiyle üretilen NiTi/Ni3Al intermetalik fonksiyonel derecelendirilmiş malzemeye borun etkisinin incelenmesi(Nevşehir Hacı Bektaş Veli Üniversitesi, 2017) Batı, Serkan; Kılıç, Musa; Biliz, İbrahim; Demir, Fatih; Batıbay, Esra
