Deformation and annealing texture in the cold rolled low carbon steels is important for sheet metal forming operations and service performance. The aim of this study is to non-destructively investigate the effect of texture on magnetic anisotropy. Various samples having different textures and residual stress states, due to different % reduction in thickness, annealing and stress relieving treatment, were prepared. Texture maps were obtained by Magnetic Barkhausen noise measurements performed with 100 steps between the ranges of 00-3600 on the surface. Microstructure investigation by optical & scanning electron microscopy; hardness and tension tests were performed; and texture was determined by X-Ray diffraction method. The results were compared, evaluated and discussed to establish relationship between texture and magnetic Barkhausen Noise emission.

Investigating the effects of quenching and tempering on steel microstructures by Magnetic Barkhausen Noise method
Gür, Cemil Hakan; Çam, İbrahim (2012-12-01)
Non-destructive evaluation of the properties of the heat treated steels is a challenging task. In this study, quenched and quenched-tempered (200°C and 600°C) SAE 1040 and SAE 4140 steels were characterized by Magnetic Barkhausen Noise (MBN) method. First, the microstructures of the samples were characterized by SEM examination and hardness measurements. Then, the MBN signals were evaluated by using a commercial Barkhausen noise system. The results showed that the MBN response of the as-quenched martensite ...
Characterization of Duplex Stainless Steel Weld Metals Obtained by Hybrid Plasma-Gas Metal Arc Welding
Yurtışık, Koray; Tirkeş, Süha; Gür, Cemil Hakan; Gürbüz, Rıza (FapUNIFESP (SciELO), 2013-07-01)
Despite its high efficiency, autogenous keyhole welding is not well-accepted for duplex stainless steels because it causes excessive ferrite in as-welded duplex microstructure, which leads to a degradation in toughness and corrosion properties of the material. Combining the deep penetration characteristics of plasma arc welding in keyhole mode and metal deposition capability of gas metal arc welding, hybrid plasma - gas metal arc welding process has considered for providing a proper duplex microstructure wi...
Investigating the Effects of Subsequent Weld Passes on Surface Residual Stresses in Steel Weldments by Magnetic Barkhausen Noise Technique
Gür, Cemil Hakan; Batıgün, Caner; Çam, İbrahim (2016-03-01)
Variations of surface residual stresses with subsequent weld passes were investigated in API 5L X70 steel plates by the magnetic barkhausen noise (MBN) technique. The plates were welded by applying a number of different passes under fully clamped conditions. After each weld pass, the MBN signal and hardness distributions on the front and back surfaces of the plates were measured. A specific calibration procedure and setup were used for conversion of the MBN signals into elastic stress values. The results we...

Investigation of SiCp reinforced aluminium matrix composites by shear and longitudinal ultrasonic waves
Gür, Cemil Hakan (2001-11-01)
SiC particulate reinforced aluminium matrix composites are attractive materials for automotive and aerospace applications because of their outstanding stiffness and strength as compared to the aluminium alloys, in addition to the low cost of particulate reinforcement. The aim of this study is to establish correlations between ultrasonic wave velocities and SiC content, microstructure and mechanical properties of SiC reinforced Al composites, Specimens were fabricated for various volume fraction and size com...
